METHOD OF PREPARING PEROXYDISULFURIC ACID Russian patent published in 1998 - IPC

Abstract RU 2120499 C1

FIELD: inorganic synthesis. SUBSTANCE: peroxydisulfuric acid salts are prepared by electrolysis of acidic ammonium sulfate solutions in presence of fluoride additives in concentration 0.1 to 1 M on anodes of glass- carbon prepared through pyrolysis of resins at 1300-2000 C. Service time of glass-carbon anode with wall thickness 3 mm is 5 years. EFFECT: intensified technology, reduced material and power consumption. 2 tbl
