Abstract

The present invention discloses a CoFeO-WTRs composite magnetic catalyst for efficiently degrading atrazine by activating peroxymonosulfate, preparation method and application thereof. The CoFeO-WTRs composite magnetic catalyst is prepared by three steps: the first step is acid-leaching of WTRs, using the WTRs as iron source to provide the iron ions required for the synthesis of CoFeO; the second step is preparing of a precursor, synthesizing CoFeOby chemical co-precipitation method and uniformly loading the prepared CoFeOon the WTRs; and the third step is calcining the precursor to synthesize the CoFeO-WTRs composite magnetic catalyst. The catalytic performance of the CoFeO-WTRs composite magnetic catalyst prepared by the present invention is evaluated using PMS as an oxidant and atrazine as a target pollutant. The CoFeO-WTRs can efficiently remove atrazine from the actual water, exhibiting good potential for practical application.
