Abstract
The processes of sorption and desorption of the mixture of copper and zinc ions in the concentration of 0,02 and 0,05 N in highly acidic cation exchangers KU-2-8 are studied. The efficiency of regeneration of the cation exchanger with 8% and 10% sulfuric acid are investigated. The conditions of electrochemical separation of mixtures of copper and zinc ions depending on the acidity of the solution and the density of the current are determined. The study has shown that it is possible not only to extract these metals on strongly acidic cations from aquatic media with repeated use of resins, but also to restore processed regeneration solutions with the help of electrolysis to obtain pure metals – copper and zinc. Therefore, the solutions are suitable for reusing.
