Title:
METHOD FOR PREPARING MODIFIED PYRITE WITH PHOTOCATALYTIC PERFORMANCE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/100226
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of sewage treatment, and particularly relates to a method for preparing a modified pyrite with a photocatalytic performance and the use thereof. The method comprises adhering a pyrite powder to the bonding surface of an adhesive tape, placing same in a silane hydrolysate for reaction, taking same out, cleaning and drying same, and removing the adhesive tape, so as to obtain a silane-treated pyrite; and then reacting the silane-treated pyrite with an anthraquinone compound, filtering same, cleaning the filtered solid, and drying same to obtain the modified pyrite powder with a photocatalytic performance. The modified pyrite with a photocatalytic performance of the present invention can effectively degrade heavy metal ions and promote and improve the degradation rate of nitrate, azo dyes, etc., by microorganisms, and the modified pyrite also has good application prospects.
