Abstract

A water treatment agent for removing contaminants through oxidation with high-activity intermediate-state pentavalent manganese consists of a manganese-containing compound, a complexing agent, and a persulfate, wherein the manganese-containing compound is bivalent manganese ions, permanganate or manganese dioxide. The molar ratio of the bivalent manganese ions, the ligand, and the persulfate is 1:1-50:1-1000. The agent removes contaminants through oxidation with high-activity intermediate-state pentavalent manganese, and has the advantages of high oxidizing ability, being capable of fast removing organic contaminants in water, and having no toxic and harmful substance produced.
