Abstract

The results of research on the electrochemical processing of acidic regeneration solutions containing heavy metals ions are presented. The use of a three-cell electrolyzer makes it possible to efficiently extract zinc, copper and nickel ions from muriatic solutions and to concentrate hydrochloric acid in the cell’s intermediate chamber. The paper studies the dependence of the current yield of heavy metals on the concentration of hydrochloric acid, the initial concentration of heavy metals in the cathode chamber, the duration of electrolysis and the concentration of hydrochloric acid in its concentrating zone. The yield of copper and zinc decreases with increasing of acidity in the initial solutions and in the intermediate chamber of the cell. The current yield of nickel is determined to be little depended on the initial concentration of hydrochloric acid. The results on the concentration of hydrochloric acid, depending on the duration of electrolysis, the initial concentration of acid and heavy metals in the catholyte are presented. Bibl. 9, Fig. 9.
