conductedfor
the
Mercury
Working
Group.
In
order
to
comply
witi
the
requirements
of
the
Resource
Conservation
and
Recovery
Act,
as
implemented
by
the
U.
S.
Environmental
Protection
Agency
(
EPA),
the
U.
S.
Department
of
Energy
(
DOE)
must
apply
amalgamation,
the
treatment
standard
for
radioactively
contaminated
mercury,
before
disposing
of
these
wastes.
The
Mercury
Working
Group
under
the
Mixed
Waste
Focus
Area
sponsored
a
demonstration
in
which
two
commercial
vendors
demonstrated
their
technologies
for
the
treatment
of
radioactive
mercury
from
various
DOE
sites.
The
project,
described
in
this
report,
addresses
the
need
for
data
on
the
vapor
pressure
and
degradation
occurring
in
amalgamated
mercury
mixed
low­
level
wastes
generated
during
these
demonstrations
under
a
variety
of
conditions.

A
set
of
experiments
studied
the
release
of
mercury
above
the
headspace
of
amalgams
as
a
function
of
temperature.
Three
temperatures
were
selected:
4
°
C,
ambient,
and
60`
C.
Results
showed
that
compounds
made
with
sulfur
do
not
release
mercury
while
those
amalgams
made
with
metals
release
mercury
at
a
level
comparable
to
that
of
pure
mercury.

Another
set
of
experiments
studied
the
degradation
of
the
amalgams
as
a
function
of
the
pH
of
the
leachant
in
which
they
were
immersed.
Four
pH
values
were
selected:
(

and
(

using

z.
The
Ieachates
were
analyzed
after
2
weeks,
1
month,
2
months,
and
3
months
for
mercury
and
trace
metals.

Even
though
the
leach
test
conditions
selected
were
unlikely
to
reflect
those
of
a
disposal
site,
the
goal
was
to
submit
the
amalgams
to
extreme
conditions
where
the
mechanisms
of
degradation,
if
any,
would
prevail.
Analytical
results
indicated
that
amalgams
prepared
with
metals
did
not
perform
well
at
low
(
acidic)
and
neutral
pH,
releasing
mercury
and
metals
into
the
Ieachate
solutions.
These
amalgams
tended
to
perform
better
in
alkaline
solution.
Additionally,
the
sulfurbased
amalgams
appeared
to
fare
better
over
the
entire
pH
range
evaluated.

1.
BACKGROUND
Significant
quantities
of
radioactive
mercury
waste
[
mixed
low­
level
waste
(
MLLW)]
are
currently
stored
at
the
U.
S.
Department
of
Ener=~
(
DOE)
facilities.
In
order
to
meet
the
U.
S.

Environmental
Protection
Agency
(
EPA)
Land
Disposal
Restrictions
(
LDR),
the
treatment
standard
for
this
type
of
waste
under
the
Resource
Conservation
and
Recovery
Act
(
RCRA),
as
set
forth
by
the
EPA
(
40
CFR
268.40),
is
amalgamation
(
AMLGM).
The
EPA
defines
the
term
as
"
amalgamation
of
liquid,
elemental
mercury
contaminated
with
radioactive
materials
utilizing
inorganic
reagents
such
as
copper,
zinc,
nickel,
gold,
and
sulfur
that
result
in
a
nonliquid,

semisolid
amalgam
and
thereby
reducing
potential
emissions
of
elemental
mercury
vapors
to
the
air.
"
The
adherence
to
a
defined
technology­
based
treatment
standard
qualifies
tie
treated
waste
as
LDR
compliant.

As
stated
in
the
EPA
definition,
the
purpose
of
the
treatment
is
to
reduce
the
emission
of
elemental
mercury
vapor
in
the
environment.
Different
metals
can
form
an
amalgam
with
mercury
(
e.
g.,
tin,

cadmium,
zinc,
and
copper),
while
sulfur
forms
mercury
sulfide
compounds.
The
EPA
has
accepted
sulfitr
as
a
possible
reagent
for
meeting
the
treatment
@.
dard.
It
has
to
be
noted
that
even
though
sulfur
fits
the
treatment
standard
for
amalgamation,
this
material
does
not
amalgamate
mercury;
it
forms
low­
volubility
mercury
compounds.
An
amalgam
is
an
alloy
containing
mercury,

and
sulfur
is
a
nonmetallic
element
however,
after
making
this
dktinction,
the
terminology
of
sulfkr­
amalgam
may
be
used
throughout
the
report.

Previous
bench­
scale
work
performed
at
the
Oak
Ridge
Y­
12
Plant
indicated
that
amalgams
of
mercury
made
with
metals
released
almost
as
much
mercury
vapor
as
pure
mercury
itself,
while
amalgams
made
with
sulfitr
released
only
small
amounts
of
mercury.*

INTRODUCTION
One
of
the
primary
performance
req~
ements
specified
in
the
Mixed
Waste
Focus
Area
(
MWFA)

Technology
Development
Requirements
Document
 
Mercury
Amalgamation
 
is
related
to
vapor
emissions:
"
The
process
must
not
release
mercury
vapors
into
the
environment
above
the
limits
established
by
the
applicable
air
permit
[
in
accordance
with
Clean
Air
Act
(
CAA)
requirements].
In
addition,
the
process
should
not
expose
operators
to
mercury
vapors
above
the
established
Threshold
Limiting
Value
(
TLV)
of
0.05
mg/
m3."
Another
part
states:
"
The
final
waste
form
must
exhibit
insignificant
decomposition
in
a
temperature
range
of
40
°
to
140"
F
and
in
environments
of
all
pH
ranges,
especially
alkaline
environments.
The
temperature
range
provided
correlates
to
environments
common
to
DOE
mixed
waste
storage
facilities.
Using
the
TLV
as
a
basis,
the
find
waste
form
must
have
a
vapor
pressure
of
less
than
10­
6torr
at
140"
F.
"

"
Vapor
pressure"
is
defined
as
the
pressure
at
which
a
liquid
or
solid
is
in
equilibrium
with
its
vapor
at
a
given
temperate.
The
property
of
vapor
pressure
depends
only
upon
the
temperature
and
the
composition
of
the
material
considered.
For
a
typical
liquid,
a
constant
and
reproducible
vapor
pressure
exists,
which
will
increase
only
with
a
temperature
increase.
3
The
description
given
by
the
MWFA
defines
the
scope
of
the
study:
(
a)
measuring
mercury
vapor
pressure
as
a
function
of
temperature
 
over
the
range
of
4
to
60"
C
 
and
(
b)
evaluating
the
effect
of
pH
on
the
possible
degradation
of
the
amalgam
and
then
correlating
this
degradation
with
the
mercury
vapor
pressure
in
the
headspace
above
the
sample
and
solution.

Two
experimental
methods
are
provided
by
the
EPA4
and
the
American
Society
for
Testing
and
Materials
(
ASTM)
5for
measuring
mercury
vapor
pressure:
the
isoteniscope
procedure
and
the
gas
saturation
procedure.
The
latter
appeared
to
be
well
suited
for
the
work
described
in
this
document.
The
modified
test
procedure
used
in
this
study
was
very
similar
to
the
static
headspace
analysis
method
used
by
Kriger
and
Turner.
b
In
this
technique,
the
mercury
vapor
pressure
is
allowed
to
reach
equilibrium
in
a
static
headspace,
and
the
mercury
concentration
(
mass/
volume)
in
the
headspace
is
subsequently
measured
using
a
commercial
mercury
vapor
analyzer.
They
demonstrated
that
a
portable
commercial
mercury
analyzer
can
provide
fast
and
reliable
measurement
of
the
mercury
content
in
a
sample
and
performed
comparative
tests
of
their
technique
and
approved
EPA
methods
(
Method
245.
1).
Satisfactory
correlations
 
from
75%
(
in
the
worst
case)
to
103%
 
were
obtained.

EQUIPMENT
3.1
MERCURY
VAPOR
ANALYZER
DESIGN
The
instrument
used
for
measurement
of
the
vapor
pressure
of
mercury
was
a
Jerome431
goldfti
mercury
vapor
analyzer
from
Arizom
Instruments
(
Phoenix,
Arizona).
This
instrument
has
a
13­
s
response
time,
is
battery
operated,
and
can
run
for
6
h
before
being
recharged.
The
digital
display
can
provide
results
in
either
milligrams
per
cubic
meter
or
nanograms.
The
range
of
detection
is
0.000
to
0.999
mg
per
cubic
meter
of
mercury.
The
sensitivity
of
the
instrument
is
0.003
mg/
m3,
which
corresponds
to
0.3
ng
of
mercury,
considering
that
the
volume
of
air
analyzed
is
87.5
ML.
This
sensitivity
is
well
below
`
theTLV
value
of
0.05
mg/
m3.
The
air
sampling
is
made
with
the
aid
of
an
internal
pump
that
operates
at
a
rate
of
750
cm3/
rnin.
The
air
flows
through
a
guard
column
packed
with
soda
lime
for
removing
moisture
and
acid
gases.
The
resulting
dry
vapor
is
deposited
onto
a
gold
film,
which
forms
an
amalgam
with
mercury,
thus
increasing
the
electrical
resistance
of
the
film.
This
specific
instrument
is
stable
and
selective
for
mercury,
and
unIike
other
ultraviolet
analyzers,
is
not
prone
to
interferences
such
as
from
water
vapor
and
hydrocarbons.
When
the
sensor
approaches
its
saturation
limi~
the
instrument
provides
a
warning.

The
regeneration
of
the
sensor
takes
about
30
min.

The
instrument

during
the
pH
tests
was
a
PS

automated
mercury
analyzer,
from
Lehman
Labs.
Its
detection
limit
is
­
5
~
g/

EPA
protocols
(

were
followed
during
use
of
this
instrument.

MERCURY
RELEASE
AS
A
FUNCTION
OF
TEMPEIUiTURE
The
objective
of
this
first
set
of
experiments
was
to
study
the
effect
of
temperature
on
the
mercury
vapors
released
from
the
various
amalgams
and
compounds.
The
Technology
Development
3
.­­
._.

Requirements
Document
(
2)
indicates
that
the
range
of
temperature
usually
found
in
DOE
MLLW
storage
varies
horn
4
to
60`
C.
Consequently,
measurements
were
made
at
the
following
temperatures:
4"
C,
ambient
(­
20
°
C),
and
60"
C.

A
weighed
sample
of
amalgam
was
placed
in
a
Kapak@
pouch,
which
was
then
closed
by
heat
sealing.
The
pouch
was
not
completely
filled
with
air
to
permit
volume
changes
during
the
experiment.
The
use
of
the
pouch
facilitated
sampling.
The
bag
collapsed
on
itself
when
the
air
was
withdrawn
for
analysis
and
was
easily
punctured
with
the
needle
of
the
syringe
used
for
sampling.
After
completion
of
the
sampling,
performed
in
triplicate,
the
bag
was
resealed.
The
same
protocol
was
followed
for
each
temperature
studied.

Preliminary
tests
were
performed
to
determine
the
need
for
dilution
of
the
headspace
samples.
It
was
found
that
some
of
the
amalgams,
as
well
as
the
mercury
standard,
saturated
the
sensor
of
the
anaIyzer
when
an
undiluted
analysis
was
performed.
Volumes
of
0.1
to
3
mL
of
the
headspace
sample
diluted
to
a
total
of
87.5
mL
by
clean
room
air
were
found
to
be
appropriate
for
use
in
this
set
of
experiments.
Measurements
were
made
at
various
time
intervals
to
veri@
that
the
data
obtained
were
representative
of
an
equilibrium
condition.

The
objectives
of
these
tests
were
to
measure
the
release
of
elemental
mercury
vapor
over
a
given
set
of
conditions
for
each
candidate
waste
form
and
to
compare
the
results
with
pure
elemental
mercury
vapor
of
untreated
waste.
The
literature
does
not
provide
tables
of
vapor
concentration
of
pure
mercury
as
a
fi.
mctionof
the
temperature
but
rather
expressed
the
vapor
pressure
as
a
function
of
the
temperature.
However,
by
using
the
ideal
gas
law
presented
in
Eq.

was
generated,

AMALGAM
DEGRADATION
AS
A
FUNCTION
OF
pH
The
objective
of
the
second
set
of
experiments
was
to
study
the
effect
of
pH
on
the
release
of
mercury
as
well
as
on
waste­
form
degradation.
Four
solutions
representing
different
pH
values
were
selected
for
that
test
1.
a
pH
of
­
12.5
(
the
pH
of
cementitious
pore
water),
prepared
from
a
saturated
solution
of
Ca(
OH)
z
in
deionized
(
DI)
water;

2.
a
near­
neutral

(
6
to

with

3.
an
acidic
pH
(­

made
with
the
recipe
for
fluid
#
1
from
the
EPA
TCLP
test
(
5.7
mL
of
gIacial
acetic
acid
plus
64.3
mL
of
1N
NaOH
solution
in
1
L
of
DI
water);
and
4.
an
acidic
pH
(­
3)
made
with
the
recipe
for
fluid
#
2
(
5.7
mL
of
glacial
acetic
acid
in
1
L
of
DI
water)
fkom
the
EPA
TCLP
test.

The
same
experimental
design
described
in
S&
t.
4
was
also
employed
in
these
tests;
however,
this
series
was
performed
at
ambient
temperature.
A
lmown
amount
of
amalgam
was
introduced
into
the
pouch
foIlowed
by
100
mL
of
the
chosen
leachant.
The
bag
was
sealed,
placed
in
a
secondary
container,
and
allowed
to
cure
at
room
temperature.
After
equilibration
for
a
selected
period
of
time,
the
Ieachate
was
removed
from
the
pouch
using
a
60­
mL
syringe.
It
was
then
filtered
using
a
0.45­
pm
syringe
Iilter
and
finally
preserved
with
1
mL
of
concentrated
ultrapure
nitric
acid.
The
solutions
were
subsequently
analyzed
for
metals
and
mercury
content.
The
samples
did
not
undergo
a
digestion
preparation
step.

For
each
time
interval
selected
(
2
weeks,
1
month,
2
months,
and
3
months),
a
blank
and
mercury
standard
were
prepared
in
triplicate
for
each
pH
value
studied.
The
four
lypes
of
amalgam
were
also
prepared
in
triplicate
for
each
period
of
time
and
pH
value.

RESULTS
OF
MERCURY
RELEASE
AS
A
FUNCTION
OF
TEMPERATURE
As
shown
in
Fig.
1
for
pure
mercury,
the
concentration
of
the
mercury
in
the
vapor
phase
is
very
sensitive
to
temperature.
In
these
tests,
the
results
obtained
at
ambient
temperature
were
quite
constant
because
of
the
small
temperature
fluctuation
existing
in
the
room;
however,
for
the
samples
maintained
in
the
refrigerator
or
in
the
oven,
large
fluctuations
were
observed
as
a
result
of
changes
in
the
temperature
of
the
chamber.
Oncethe
doorwasopenedto
permitsamplingof
the
first
bag,
the
temperature
changed;
consequently,
the
data
obtained
no
longer
reflected
the
targeted
temperature.

Some
variation
is
reflected
in
the
data
presented
in
Tables
2,
3,
and
4.
It
must
be
noted
that
the
mercury
used
as
the
standard
for
our
tests
had
been
used
for
previous
experiments;
therefore,
the
data
obtained
might
differ
from
the
theoretical
values
because
of
the
contamination
present
in
this
sample.

6.1
TESTS
PERFORMED
AT
4
°
C
Thesesamples
were
placedin
a
refrigeratorsetfor
4
°
C.
After
3
days,
a
first
set
of
measurements
was
taken.
A
3­
mL
syringe
was
used
for
sampling
the
headspace
in
each
bag
and
injecting
tie
sample
into
the
septum
of
the
mercury
analyzer.
The
tests
were
run
in
triplicate
and
then
averaged.

Data
found
in
the
literature
indicate
that
the
mercury
concentration
in
tie
headspace
should
be
3.20
mg/
m3
at
4
°
C.
However,
because
of
the
rise
in
temperature
caused
by
opening
the
refrigerator
door,
some
of
the
data
were
not
collected
at
a
temperature
of
4"
C.
The
data
obtained
at
three
different
times
(
after
3,
11,
and
13
days)
are
provided
in
Table
2.
Figure
2
illustrates
the
average
results
obtained
for
each
series
of
amalgam
studied
as
well
as
a
blank
and
a
mercury
standard.
The
theoretical
values
for
pure
mercury
at
4,
7,
and
10
°
C
are
also
presented
in
the
plot.

RESULTS
OF
MERCURY
DEGRADATION
AS
A
FUNCTION
OF
pH
In
this
set
of
experiments,
triplicate
analyses
were
performed
for
each
time
interval
and
pH
evaluated.
The
metal
concentrations,
expressed
in
milligrams
per
liter,
were
determined
by
ICP,

while
the
mercury
concentrations,
expressed
in
micrograms
per
liter,
were
measured
by
cold
vapor
atomic
absorption
(
CVAA).
The
data
generated
after
2
weeks,
1
month,
2
months,
and
3
months
of
cure
are
presented
in
Tables
A.
l­
A.
16
located
in
Appendix
A.
A
compilation
of
the
average
data
obtained
for
each
series
is
provided
in
Appendix
B,
Tables
B.
1­
B.
6.
The
weight
of
the
amalgam
used
as
well
as
the
pH
of
the
initial
solution
and
the
pH
after
cure
are
provided.

It
is
interesting
to
note
that
heterogeneity
is
observed
in
the
mercury
data
obtained
for
some
samples
prepared
in
triplicate.
Many
of
the
samples
presenting
these
differences
were
rerun
to
13
..­

confirm
the
results,
and
the
analyses
confirm
the
heterogeneity
in
many
cases.
This
may
be
explained
by
the
presence
of
mercury
that
had
not
completely
reacted
with
the
amalgamating
material.
This
hypothesis
is
very
likely
to
be
the
case
for
the
FERN
samples.
During
the
sample
preparation,
small
spheres
of
shiny
metallic
mercury
were
observed
in
the
black
material,
providing
evidence
that
some
mercury
did
not
react
completely.
For
the
FERN
and
LANL
series,
with
the
black
mercury
sulfide
material,
this
observation
was
readily
made;
however,
for
the
gray
OR
and
ID
amalgams,
it
was
difficult
to
note.
A
second
hypothesis
would
be
the
presence
in
the
leachate
of
small
particulate
of
HgS
that
were
not
captured
by
the
0.45­
pm
filter
used.
This
obsemation
was
noted
especially
for
the
ID
series,
followed,
to
a
lesser
degree,
by
the
OR
series
and
then
by
the
FERN
and
LANL
series.

7.1
CHANGES
IN
THE
FINAL
pH
OF
THE
LEACHATES
Except
for
the
blank
and
mercury
standard
series,
changes
in
the
final
pH
values
of
the
solutions
were
observed.
At
pH
3,
all
the
solutions
containing
the
various
amalgams
exhibited
a
final
increase
in
pH
with
time.
The
amalgam
made
with
the
ID
series
appeam
to
be
the
one
for
which
tie
pH
increased
the
most.
At
pH
5,
the
FERN
amalgams
appear
to
produce
the
highest
pH
increase.
At
higher
pH
values,
the
two
types
of
waste
form
are
diverging:
for
the
suIfur
amalgams,

the
fti
pH
of
the
solution
decreases
slightly
at
pH
7
and
severely
at
pH
12.5,
while
the
metalbased
amalgams
show
an
increase
for
pH
7
and
a
small
decrease
for
pH
12.5.
These
changes
are
illumated
in
Figs.
5­
8.
The
reasons
for
this
are
discussed
in
Sect.
8.1.

MERCURY
LEACHING
RESULTS
The
average
mercury
leaching
results
are
compiled
for
easy
comparison
in
Table
5.
The
results
are
expressed
in

All
the
amalgams
show
a
decrease
in
the
leachability
of
mercury
compared
with
the
pure
mercury
standard;
however,
the
scale
of
the
reduction
is
different.

of

at

These
changes
are
illustrated
in
Figs.

The
two
processes
behave
very
differently
depending
upon
pH.
Acidic
solutions
appear
to
have
a
lesser
deleterious
effect
upon
the
sulfur­
based
amalgams
than
the
metal­
based
ones,
which
can
release
significant
amounts
of
mercury
(
especially
the
ID
series).
Comparatively,
the
more
basic
solutions
appear
to
be
less
aggressive
on
the
metal­
based
amalgams
than
those
solutions
made
with
sulfur.

inherent
in
the
experimental
protocol
followed
 
the
high
level
of
sodium
found
for
a
pH
of
5
is
caused
by
the
presence
of
NaOH
in
TCLP
fluid
#
2;
at
a
pH
of
12.5,
the
calcium
hydroxide
added
for
the
"

preparation
of
the
saturated
Ca(
OH)
zexplains
the
high
calcium
content.
Low
concentrations
of
potassium,
sodium,
silicon,
and
zinc
were
found
in
this
series.
The
mercury
series
(
Fig.
14)
shows
that
trace
copper,
silicon,
and
aluminum
were
present
as
contaminants
in
the
mercury
used
for
the
experiments.

Data
horn
the
FERN
series
(
Fig.
15)
show
that
the
following
metals
were
found
at
low
concentrations
in
the
leaching
solutions:
aluminum,
iron,
magnesium,
and
strontium.
The
concentrations
of
metals
leached
were
higher
at
low
pH
values
than
at
higher
ones.
The
concentration
of
calcium
found
in
the
Ieachate
was
high,
around
2000
mg/
L.
From
the
same
process,
tie
LANL
series
(
Fig.
16)
also
presented
higher
concentrations
of
calcium
than
those
in
the
blank;
however,
these
concentrations
were
not
as
high
as
those
observed
in
the
FERN
series.

The
concentrations
of
aluminum,
iron,
magnesium,
potassium,
sodium,
and
silicon
present
in
the
~
g~
were
higher
th~
~
ose

series­

Data
from
the
OR
series
(
Fig.
17)
showed
that
small
concentrations
of
aluminum,
boron,
iron,

potassium,
and
silicon
are
also
present
in
the
leachates.
At
low
pH
values,
high
concentrations
of
zinc
and
magnesium
were
found
in
the
leachates
but
were
absent
at
neutral
values
or
basic
pHs.
It
is
interesting
to
observe
that
in
contrast
to
the
sulfur­
based
amalgams,
the
metal­
based
type
appears
to
consume
calcium
at
high
pH.
The
ID
amalgams
(
Fig.
18)
released
aluminum,
boron,
iron,

potassium,
and
silicon.
As
in
the
OR
series,
magnesium
and
zinc
were
released
at
acidic
pHs.
The
calcium
release
follows
the
same
pattern
as
the
OR
series;
concentrations
at
pH
values
of
12.5
were
lower
than
those
for
the
blank
series.
The
sodium
concentrations
appear
to
be
higher
than
those
for
the
other
series.

DISCUSSION
OF
RESULTS
8.1
AMALGAMATED
MERCURY
TheacidicpHvalueswereexpectedto
havea
moredeleteriouseffectuponthe
amalgamwhen
made
with
acid­
reactive
metals
(
zinc,
aluminum,
cadmium,
copper)
because
of
the
generation
of
hydrogen
that
occurs
at
lower
pH
values.
At
higher
pH
values,
hydrated
oxides
of
mercury
tend
to
form
and
are
therefore
expected
to
fare
better.
Amalgamated
mercury
did
not
perform
as
well
as
the
sulfur­
based
mercuric
sulfide.
This
may
be
explained
by
the
well­
known
fact
that
mercury,

once
amalgamated
with
another
metal
such
as
zinc,
copper,
or
aluminum,
causes
the
metal
to
become
very
reactive
in
water
and
especially
in
acidic
solutions.
These
metals
will
even
slowly
react
with
pure
water,
liberating
hydrogen,
and
enter
solution
as
the
metal
cation.
This
process
is
slow
kinetically;
however,
when
mercury
amalgamates
with
the
metal,
the
hydrogen
potential
of
the
metal
reacting
with
water
or
acid
is
lowered
considerably
and
becomes
more
reactive
as
a
result.
7
After
all
the
metal
dissolves,
the
elemental
mercury
remains
behind.
This
reactively
with
either
acid
or
water
is
depicted
in
the
following
equations:

(

Both
reactions
produce
arise
in
pH,
as
illustrated
by
Figs.
7
and
8.
From
the
ICP
data,
it
appears
that
zinc
was
likely
used
as
an
amalgamating
metal.
Because
of
the
enhancement
in
reactivity
of
the
metal
toward
water
or
acidic
solutions,
mercury
amalgamation
using
such
metals
will
result
in
the
re­
formation
of
free
elemental
mercury
released
to
the
environment
over
time,
if
the
waste
form
is
exposed
to
such
conditions.

8.2
MERCURIC
SULFIDE
IMMOBILIZATION
Mercury
is
found
in
mture
as
the
ve~
insoluble
mineral
cinnabar
(
HgS)
and
is
also
known
as
mercuric
sulfide.
The
sulfide
is
not
reactive
to
any
appreciable
extent
in
water,
with
a
volubility
product
~
of
only
10­
15for
the
black
allotropic
form.
The
sulfide
is
reactive
only
in
acid
and
slowly
reactive
in
oxygemted
alkaline
solution,
where
it
can
be
oxidized
to
soluble
mercuric
sulfate
or
sometimes
HgOH+.
These
first
two
reactions
of
mercuric
sulfide
can
be
depicted
as
follows:

Hg
 
M*+
2H++
M2++
Hg0+
H2
(
g)~

and
HgS
+
OH
 
+
20z(
g)
+
Hg(
OH)+
+
SO~"
(
4)

(
5)

In
Eq.(
4),
acid
is
consumed
as
mercury
enters
solution
and
the
pH
can
be
expected
to
rise,
as
shown
in
Figs.
5
and
6.
EventuaUy,
the
mercury
cation
can
react
with
hydroxyl
anion,
when
the
pH
rises
sufficiently,
and
form
moderately
insoluble
hydrates
of
mercury@)
oxide
@
gO).

In
an
alkaline
solution,
with
air
present
above
the
solution,
as
was
found
in
the
experimental
setup,

the
highly
insoluble
HgS
can
slowly
be
oxidized
to
more
soluble
mercuric
sulfate.
In
Eq.
(
5),
the
hydroxyl
anion
is
consumed,
therefore
causing
a
drop
in
pH,
as
shown
in
Figs.
5
and
6.
The
reactions
of
HgS
in
an
acid
or
base
are
numerous;
therefore,
the
reactions
shown
in
Eqs.
(
4)
and
(
5)
are
probable
but
not
the
only
ones
possible.
Eventually,
mercury
in
neutral
and
alkaline
solution
will
precipitate
as
oxide,
as
shown
in
Eq.
(
6):

Hg(
O~'
+
OH­
%
HgO
~
+
HZO
.
(
6)

Since
the
reactivity
of
HgS
in
neutral
water
is
far
too
slow
to
consider
and
the
oxidation
to
soluble
sulfate
in
alkaIine
solution
is
slow,
sulfide
is
a
good
form
to
bind
elemental
mercury.

CONCLUSIONS
Two
different
processes
for
treatment
of
radioactively
contaminated
mercury
were
evaluated:
one
process
relied
upon
amalgamation
with
metals
and
the
other
depended
on
the
formation
of
mercuric
compounds
with
sulk.
In
the
set
of
experiments
that
evaluated
the
release
of
mercury
vapor
in
the
headspace
as
a
function
of
temperature,
the
amalgams
made
with
metals
released
as
much
mercury
as
tie
standard
pure
mercury
added
as
a
control.
This
observation
was
made
at
all
three
temperatures
investigated,
that
is,
4,
20,
and
60
°
C.
On
the
contrary,
the
compounds
of
mercury
sulfide
did
not
release
mercury
in
the
headspace.
Even
at
60"
C,
the
concentration
of
mercury
present
in
the
headspace
of
sulfide
compounds
did
not
exceed
1
mg/
m3,
while
the
metal­
based
amalgams
could
be
as
high
as
260
mg/
m3.
This
finding
corroborates
the
results
obtained
by
Gorin
et
al.
(
1)
in
their
experimental
work
as
well
as
those
found
in
the
literature'.

When
leached
in
various
solutions,
the
metal­
based
amalgams
appeared
to
degrade
more
than
the
sulfur­
based
compounds,
even
though
the
duration
of
the
tests
was
short
(
3
months).
Some
variabili~
was
found
in
the
mercury
leaching
results.
This
could
be
caused
by
heterogeneity
of
the
samples
themselves;
that
is,
all
the
mercury
may
not
have
reacted
during
the
treatment.
This
was
corroborated
by
the
observation
of
a
few
tiny
droplets
of
shiny
mercury
in
the
black
FERN
sulfur­
based
mercury
compound.
Another
cause
could
be
the
presence
in
the
leachate
of
small
insoluble
particulate
of
mercuric
sulfide
or
compounds
that
were
not
captured
by
step­
the
0.45­~
m
filter­
and
were
analyzed
as
ionic
mercury
from
the
leachate.
