A method for measuring the concentration of contaminants of cobalt and copper and removal of these impurities from an electrolyte solution for the electrolytic extraction of zinc

摘要

concentrations of cobalt and copper in a elektrolytlu00f6sung for the electrolytic extraction of zinc can at any time during the electrolytic extraction by continuous removal of a lu00f6sungsprobe whose dilution, addition of a farbreagens to lu00f6sungsst rome and spektrophotometrische analysis of the solution to be measured.cobalt and copper can $a as a harmful contaminants continuously and automatically by measuring their concentrations according to the above procedure and by the addition of ausfu00e4llungsreagenzien in quantity, with the aid of a microcomputer on the basis of the above analysis are calculated wi rd, are removed.
