Abstract
A method of electrochemical purification of aqueous solutions from metal ions is proposed. The method is based on the use of electrochemical cell separated by a passive membrane, and substitution of metal ions by hydrogen ions. The conditions enhancing the effects of concentrating and removal of metal ions form solutions with low concentrations of the salts of weakly and strongly dissociating acids are determined.
