I'd try this: small scale, look for sulfur precipitation (may clear with further addition of peroxide), nitrogen gas bubbling and further NOx generation (red-brown fumes, ie. in a hood) possible. Get a recipie that works and share it in glory!

You might look into adding hydrogen peroxide, perborate or some persulfate derivative.

Subject: [DCHAS-L] neutralizing ammonium sulfide

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,
