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

Re: Disposal of chemical solutions
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."

Re: Disposal of chemical solutions
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.

Re: Disposal of chemical solutions
Does anyone still use vermiculite for evaporation and disposal of chemicals?
