Electrochemical production of magnesium peroxodisulfate used as active ingredient in oxidation agents and in disinfectants is carried out using magnesium sulfate as anolyte and sulfuric acid as catholyte

摘要

Magnesium peroxodisulfate is electrochemically produced by electrolysing an anolyte solution containing 2.5-4.0 mol/l magnesium sulfate in an electrochemical cell separated by cation exchange membranes at 30-70 deg C. The catholyte used is 1-7 molar sulfuric acid.
