Increasing the Efficiency of Electromembrane Processes in the Area of Electrochemical Cadmium Plating

At the pilot plant, the main parameters of the electromembrane process of extracting cadmium ions from a sulphate-ammonium cadmium electrolyte with high performance characteristics and a bath for rinsing cadmium parts in stagnant water (collection baths) have been determined. It is shown that the degree of extraction under stationary conditions is about 99%, which corresponds to the values obtained with other sulfate-ammonium cadmium plating electrolytes and allows us to recommend the investigated electrolyte for use in industry.
