Description
Polarization measurements and gas chromatographic analysis of the composition of gaseous electrolysis products were used to investigate the effect of phosphate, sulfate and perchlorate on the kinetics of the evolution of chlorine and oxygen at ruthenium-titanium oxide anodes (ORTA) under the conditions of chlorine electrolysis. It was found that at i = 0.2 A/cm2 the addition of NaH2PO4 and Na2SO4 to the chloride solution inhibits the evolution of chlorine, indicating the predominant adsorption of phosphate and sulfate ions on the ORTA surface. At a constant potential, the evolution rate of oxygen from solutions of NaClO4, NaH2PO4, Na2SO4 and NaCl of equal concentration with a pH approximately 1.6 decreases in the order perchlorate greater than chloride greater than sulfate greater than phosphate
