Demystify:
Is the ammonium sulfide the final waste product? If so, it would need to be managed under Ohio's hazardous waste rules as a D001 ignitable, D002 (corrosive) and likely D003 (reactive) waste; DOT UN2683 8(6.1,3) pgII.
We are using ammonium sulfide in excess in a reaction in water. What is the proper way to dispose of the aqueous ammonium sulfide? We are concerned that if we add bleach we will make chloramine. Does anyone have a way to convert the
ammonium sulfide to ammonium sulfate?
