MEMBRANE ELECTHOLISER FOR EXTRACTION OF NON-FERROUS METALS IONS OUT OF USED TECHNOLOGICAL SOLUTIONS

Abstract

Analysis of methods of decreasing of harmful substances wastes — cations of non-ferrous metals into the objects of surrounding was done. Attention was focused on the process of electrochemical regeneration of some used solutions of etching copper. Membrane electrolyzer was made for that purpose. Conditions of extraction of Cuprum ions out of used solutions and setting hard or powder copper electrodeposition were found out. Possibility of formation not only safe but resource-reserved process of etching copper in used solutions was shown.
