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!

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,Nickie NortonResearch ChemistThe Shepherd Chemical Company4900 Beech StreetNorwood, OH 45212513-842-9332--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas
