Title:
CATALYST FOR USE IN REMOVING ANTIBIOTICS IN WATER BODY BY ACTIVATING PEROXYMONOSULFATE, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/227213
Kind Code:
A1
Abstract:
A catalyst for use in removing antibiotics in a water body by activating peroxymonosulfate, a preparation method therefor, and an application thereof. The method comprises the following steps: mixing the catalyst with an antibiotic water body, stirring, adding peroxymonosulfate for a degradation reaction, and completing removal of antibiotics in the water body, wherein the catalyst is prepared by calcinating a waste lithium battery as a raw material, and the catalyst contains LiCoO2 and Co3O4. Efficient degradation of the antibiotics in the water body can be realized by mixing a heterogeneous catalyst prepared by using the waste lithium battery as the raw material and peroxymonosulfate with an antibiotics-containing water body for the degradation reaction, and the present invention has the advantages of being easy to operate, low in treatment costs, wide in application range, high in treatment efficiency, good in treatment effect, high in reusability, environmentally friendly, etc., and good application value and application prospects.
