Post by remlap12 »

Hi all,
I'm doing a clean up and need your help regarding the safe disposal of some solutions please.
I have printed of a very helpful document that I found on this site, but some things I have aren't listed.
Here goes,
polyvinyl solution
lead carbonate 0.1M
dichloroethane (dichloromethane is listed)
lithium carbonate 0.5M
read lead and sand mix
iron III chloride
bismuth carbonate 0.1M

Many thanks
Helen [-o<

Red Lead & Sand mix is pickup or collection.
Do you have the CSIS ?
Page 142 Lead II Carbonate right hand corner 39 is the waste number, 39 tells you want to do.
"For solutions, add sodium sulphide, Sodium hydroxide or Sodium carbonate, stir and place the mixture in the appropriate waste bottle. When settled, the clear solution may be decanted and washed down the sink. "

Dichloromethane is a 6 page 99 right hand corner a 6 6 tell us want to do.
"Absorb onto vermiculite perlite cat litter or paper towels. Place in fume cupboard and allow chemical to evaporate. Place vermiculite, perlite or cat litter in a plastic bag, seal and place in garbage."
Lithium Carbonate is a 14,
"Transfer to a plastic bucket, Dilute and neutralise with 2M Hydrochloric acid. Carry out this task slowly as heat may be evolved from this reaction."
Iron II Chloride is 2
"Absorb using a mop cloth or paper towel, rinse solutions down the sink. Place the wet paper towel in the garbage.

Lucky last Bismuth Carbonate is a 37
" Add sodium sulfite, sodium hydroxide or sodium carbonate, stir and pour the mixture into the heavy metals waste bottle. When settled the clear solution may be decanted and washed down the sink."

If you are a DEC school, your principal BY LAW must have a copy of the CSIS near his/her office. Photo copy the bit you need and keep it in the prep room.

Hi all,

I have a mixed solution containing Iron(III) Thiocyanate, Potassium Thiocyanate, Iron(III) Chloride, and Silver Nitrate. I was wondering if anyone could help me with how to dispose of this?
To my understanding, the Silver Nitrate has precipitated out of the solution into a solid (I do have solids at the bottom of the beaker, so I am assuming I'm correct in regards to that?).
I have roughly 100mL-150mL of the solution.

Many Thanks :)
Regards, Labbie Seth :thumbup:

I would put it in an ice cream container, leave it to evaporate, and then scrape the residue into the bin. Get as much out as you can with a damp paper towel, then rinse the container for re-use. Problem solved! Nothing you listed is particularly dangerous, and it's a very small amount.

A school subscription to RiskAssess would be a much more reliable source of information. I'm not sure if there have been online updates but the CSIS is nearly 30 years old so not exactly up to date... I'm in a private school so I don't have access to it online.

We have RA, it's very good...but sometimes there is this statement way to much 'Retain for collection by a waste service." Sometimes I'd like the old school way of treating and disposing of it ourselves.

In that case, Appendix E is the section you want (You definitely don't want the whole thing!). But like I said, I only have the paper copy (which is 2 leaver arch folders full plus a bit more...). Hopefully a public school labbie will be able to help.
