The objects of study were alloys of ruthenium with neodymium, erbium, and additives of elements from the iron triad, used as anodes in the electrosynthesis of sodium peroxoborate. The study of the kinetics of anode oxidation was effected by the method of polarization measurements in different conditions. For comparison, the kinetics of the anode behavior of a platinum electrode was investigated in similar conditions. The results of the polarization measurements on a Ru/sub 2/Er anode-alloy are shown. The established facts coincide with the hypothesis that the kinetics of the electrooxidation of the carbonate-borate electrolytes in the synthesis of sodium peroxoborate is described by the equation of an irreversible wave, and the magnitude of the electrochemical and diffusion polarization depends on the nature and quantity of the iron triad element in the alloy of ruthenium with erbium (or neodymium).
