CoFe2O4-WTRs Composite Magnetic Catalyst, Preparation Method and Application Thereof

摘要

The present invention discloses a CoFe₂O₄-WTRs composite magnetic catalyst for efficiently degrading atrazine by activating peroxymonosulfate, preparation method and application thereof. The CoFe₂O₄-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 CoFe₂O₄; the second step is preparing of a precursor, synthesizing CoFe₂O₄ by chemical co-precipitation method and uniformly loading the prepared CoFe₂O₄ on the WTRs; and the third step is calcining the precursor to synthesize the CoFe₂O₄-WTRs composite magnetic catalyst. The catalytic performance of the CoFe₂O₄-WTRs composite magnetic catalyst prepared by the present invention is evaluated using PMS as an oxidant and atrazine as a target pollutant. The CoFe₂O₄-WTRs can efficiently remove atrazine from the actual water, exhibiting good potential for practical application.
