ABSTRACT
The article presents results of the study of the process of electroevolution of copper from regeneration solutions in one- and two-chamber electrolyzers at different concentrations of sulfuric acid and solutions of copper chlorides at different concentrations of hydrochloric acid - in a three-chamber electrolyzer. The conditions of electrochemical recovery of heavy metals from acidic and saline solutions are determined. It is shown that the most effective recovery of heavy metal cations from hydrochloric acid solutions occurs in three-chamber electrolyzers. On the basis of the results obtained, a technological scheme of a local plant for treatment of washing water of galvanic industries is proposed.
