INFLUENCE OF IMPURITIES IN ELECTROLYTE (USING THE EXAMPLE OF TIN, GERMANIUM, AND ANTIMONY) ON CURRENT EFFICIENCY OF ZINC

Abstract

There was investigated influence tin, germanium and antimony, as well as animal glue on the current yield (η) and specific energy consumption during zinc electrolysis. There were received adequate regression models of dependences of η and W on cathode current density and animal glue in electrolyte at constant temperature. There were defined ranks of independent variables according with intensity of influence on η value. They are distributed in cluster in the following way (according with decreasing of impact): Ge, Sn, Sb. There was empirically established that antimony in the range of 0,001–0,150 mg/l increases the current efficiency of zinc.
