Cadmium reduction in solutions at steady-state and pulse electrolysis has been studied. It was established that polarization results in cadmium formation at potentials 1 V larger than equilibrium one. In 0.25-1.0 molar solutions of CdCl2 concentrated depolarization leads to removement of the beginning of cadmium reduction by 0.3 V. Photographs of SEM are presented and effect of electrolysis characteristics on the morphology of cathode deposit is shown.
