摘要:
A process for preparing peroxydisulfates by electrolysis in a diaphragm cell uses a diaphragm, the active part of which comprises a cation exchange polymer made up of a membrane with a sulfonated polystyrene base resin supported by a polypropylene fabric. The process is applicable to the preparation of peroxydisulfates of alkali metals and of ammonium.
