safe disposal of chemicals

Hi Folks,

An old friend of mine in San Angelo Tx had a darkroom in his garage.
He went through a LOT of chemicals processing film etc, an just dumped
the waste in his yard. He was rewarded by a big green patch in his
grass. I don't think that most of the chemicals used in processing
film are particularly toxic. I will concede that he did mostly Black
and White, and some Cibachrome. Long time ago...

However, you've gotten my curiosity up. I have seen jewelers use
cyanide solutions for some processes. What do you do with old
cyanide? If you casually mixed it with some acid, we might be reading
about you in the morning paper. It worries me to think about someone
mixing chemicals together to "neutralize" them without being enough of
a chemist to know what the process will yield. If you had a vacuum
pump, you might be able to suck the water out of salt compounds, but
at what risk of sucking HCl or H2SO4 out as well,especially if the PH
has been adjusted with acids? I wouldn't use my good pump...

I think that the SMART thing to do is to collect the compatible
chemicals in 5 gallon containers, and haul them to someone who knows
what to do with them. Or else, do a lot of homework, to make sure what
you want to do is safe.

It is amazing how useful a city sewer with the gigantic dilution ratio
it offers is to the home tinkerer with occasional chemical usage!

Is'nt Chlorox a compound which liberates chlorine gas on contact with acid?
Chlorine is dangerous!

Yes and? One will note that such things are often found under your
kitchen sink. Never mix chlorine bleach with cleaning ammonia, unless
you have your NBC mask on. This does however work fairly well if you
have a mouse or roach problem and you go on vacation for a couple of
days......

This is NOT recommended if you live in an apartment or condo.....

I've wondered about that ....

They combine with the bases forming salts. I'm reminded of a highschool(?)
teacher story...

Perhaps not! I don't know the conditions for these two chemicals to react
to produce nitrogen trichloride, but if you got them right,you would not
have mouse or raoch problems, but a rehousing problem!

NCl3 (Chloramine) a yellow oily thermally unstable explosive liquid is
prepared by bubbling chlorine gas through a heated concentrated ammonia
solution. The simple mixing of cleaning (3%) ammonia water with HCl may
indeed produce some small quantity of Chloramine but never enough to be an
explosion hazard. The principle product of NH3 (aq) with HCl (aq) is NH4Cl
(Ammonium Chloride, Sal Ammoniac[salt of ammonia])

mixing chlorine and ammonia releases free chlorine. To really amuse
your friends, drop a pool tablet into a bucket of ammonia cleaner.
Leave of course....

Um... you mis-spelled "aBuse"

And I'd add the suggestion that you not just leave, but leave
IMMEDIATELY, and at a high rate of speed, preferably running into
whatever wind may be blowing. Of course, this assumes you aren't
interested in spending the rest of your life (don't worry, it'll be
fairly short) coughing your lungs out in little bloody globs...

As I indicated, it does kill roaches and mice pretty well.... and by
definition is a WMD.

Then of course we can simply pop the back of the refridgerator off and
crack the coils, while letting the escaping refridgerant pass through
a flame, making phosgene...which also killes mice and roaches.....

Kitchen sink chemistry is soooo interesting....
