Comparative Analysis of Chemical Treatment for Hexavalent Chromium Removal from Electrolytes (Dimensional Electrochemical Machining)
https://doi.org/10.18412/1816-0395-2013-5-42-43
Abstract
There were undertaking studies for selection of different chemical agents for hexavalent chromium removal from solutions. There was recommended chemical treatment with using of Na2SO3 for spent electrolytes from electrochemical treatment of nickel-chromium alloys. For electrolytes with closed system is recommended use compound electrolytes with adding of barium salts in amount from o,5 to 3% depending on chromium quantity in alloy; in doing so improving output parameters of anode treatment and toxic hexavalent chromium removing.
