Abstract: 
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.
