I would argue this is not "waste treatment" unless I, the chemist responsible for the process, defined the ammonium sulfide as "waste."

Get a recipie that works and share it in glory!

--- 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**acsdchasHi 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,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
