Radioactivity measurements and gas chromatography were used to study and compare features of anodic dissolution of platinum and platinum coatings from platinized titanium anodes, and oxygen evolution as functions of the electrolysis parameters of current density, temperature, and concentration in electrolytes with low sodium chloride content. Quantities representing the ratio of anodic platinum dissolution rates and oxygen evolution were calculated. The results showed that analogies exist between rates of platinum dissolution, and oxygen evolution but these ratios are not constant when the electrolysis parameters are varied within wide limits. A correlation was observed for dilute solutions and electrolysis temperatures enabling one to estimate the corrosion rates of platinized titanium anodes from the oxygen content of the electrolytic gas.
