Possibility of purification of electrolyte of chromium plating from impurities of caiions of iron and copper by their transfer in insoluble chromates is investigated. It is shown, that at re- peated dilution of electrolyte by distilled water and the subsequent boiling in a deposit chromates of iron and copper, which separate filtering, drop out. The cleared filtrate concentrates at evapora- tion of water at the expense of heating.
