Demystify: 

Would suggest that the easiest and safest might be to precipitate the sulfide with a soluble iron solution.

Hi All,

 

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?

 

Thank you,
