88 results about "Persulfate" patented technology

A persulfate (sometimes known as peroxysulfate or peroxodisulfate) is a compound containing the anions SO²⁻₅ or S₂O²⁻₈. The anion SO²⁻₅ contains one peroxide group per sulfur center, whereas in S₂O²⁻₈, the peroxide group bridges the sulfur atoms. In both cases, sulfur adopts the normal tetrahedral geometry typical for the S(VI) oxidation state. These salts are strong oxidizers.
