Abstract
A water treatment agent for removing pollutant by reinforcing potassium permanganate with intermediate manganese consists of a potassium permanganate and a chelating agent, or, alternatively, consists of a potassium permanganate, a chelating agent and an inducer. The chelating agent is capable of forming a coordination complex with the intermediate manganese which is produced during the reaction of potassium permanganate and organic substance. Thus self decomposition of intermediate manganese is reduced so that the effective utilization rate is increased and the capability for potassium permanganate to degrade organic pollutants is enhanced. The inducer accelerates the production of the intermediate manganese and increases the utilization rate so that the capability of potassium permanganate for degrading the organic pollutants is further enhanced.
