Peroxosulfates
Peroxosulfates are a group of chemical compounds containing the peroxosulfate anion, S2O8 2−. This anion is characterized by a peroxide bond (-O-O-) bridging two sulfate groups. The most common peroxosulfates are potassium peroxodisulfate (K2S2O8), ammonium peroxodisulfate ((NH4)2S2O8), and sodium peroxodisulfate (Na2S2O8). These compounds are powerful oxidizing agents and are often produced by the electrolysis of sulfate or bisulfate solutions.
Peroxosulfates find widespread industrial applications. They are frequently used as initiators in free-radical polymerization processes for
