The term persulfate (also known as peroxysulfate) refers to ions or compounds with more oxygen than normal sulfates.
These do not have sulfur in a different oxidation state; rather, they contain peroxide units, where two oxygens take the place of one in a normal sulfate; the oxygen atoms are in oxidation state −1. Persulfate is another commonly used oxidizing agent for in-situ chemical oxidation applications. It is most frequently applied in the subsurface as sodium persulfate (Na2S2O8). The reaction that occurs produces a strong oxidizer (the persulfate radical).
The main forms are peroxomonosulfates and peroxodisulfates.
