NOVELTY - A defective carbon material is prepared by performing plasma etching on the carbon material to obtain the defective carbon material. USE - Method for preparing defective carbon material used in activating oxidant to degrade organic pollutants (claimed). ADVANTAGE - The product can effectively activate persulfate, peroxyacetic acid and ozone, and can effectively degrade organic pollutants in sewage. The preparation is simple preparation process, easy operation and low-cost, is suitable for industrialization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for application of defective carbon material comprising mixing the organic pollutant wastewater to be processed, oxidant and defective carbon materials, and performing stirring treatment. The oxidant includes persulfate, peroxyacetic acid or saturated ozone water.
