(57) [Summary] [PROBLEMS] The use of an accelerator can be completely omitted, An industrial process for producing ammonium peroxodisulfate and alkali metal peroxodisulfate, wherein the electrolysis is carried out at low current densities, is presented. SOLUTION: In the method for producing peroxodisulfate, for example, ammonium peroxodisulfate, sodium peroxodisulfate and potassium peroxodisulfate by anodizing an electrolyte containing sulfate and / or hydrogensulfate, A diamond layer disposed on a conductive support and rendered conductive by doping with a trivalent or pentavalent element is used as the anode and no accelerator is added to the anolyte. |
