Abstract

Sodium peroxodisulfate is produced by direct electrolysis by electrolyzing, at 0.3 to 1.2 amperes per square centimeter, a solution containing sodium sulfate and sulfuric acid in such quantity that the solubility of the sodium peroxodisulfate formed amounts to less than 0.6 mole per liter, and maintaining the concentration of sodium sulfate and sulfuric acid substantially constant during the electrolysis.
