peroxysulfate
Peroxysulfate is a general term for compounds containing the peroxydisulfate anion, S2O8 2−. These are strong oxidizing agents. The most common peroxysulfate is ammonium peroxydisulfate (APS), also known as ammonium persulfate. Other important examples include potassium peroxydisulfate and sodium peroxydisulfate. Peroxysulfates are typically white, water-soluble solids.
The peroxydisulfate anion has a central peroxide bond (O−O) linking two sulfate groups. This peroxide bond is
Peroxysulfates find widespread industrial applications. They are used as initiators for free-radical polymerization in the production
