General description

Sodium persulfate (Sodium peroxodisulfate) is an inorganic sodium salt. It is a cheap, eco-friendly oxidizing reagent. It is widely employed in bleaches and hair-coloring formulations.

Application

Sodium persulfate (Sodium peroxodisulfate) may be employed as an oxidizing reagent for the palladium-catalyzed C-H bond functionalization reaction of O-phenylcarbamates with arenes. It may be used to compose the initiator solution required for the preparation of hydroxyethyl methacrylate (HEMA) gel disks.

Contaminant destruction with in situ chemical oxidation (ISCO) using persulfate (peroxydisulfate, S2O8(2-)) can be enhanced by activation, which increases the rate of persulfate decomposition to sulfate radicals (SO4*-). This step initiates a chain of radical reactions involving species (including SO4*-
