Abstract

The invention discloses a method for degrading sulfamethoxazole in wastewater by activating persulfate with a magnetic two-dimensional Mxene / CuFeO2 catalyst, and belongs to the field of water treatment. The invention aims to solve the problems of low efficiency and difficult catalyst recovery of the existing persulfate catalytic activation technology, and a more efficient, economic and environment-friendly activation method is developed. The sulfamethoxazole antibiotic is selected as a typical refractory organic pollutant in the water body. According to the method, the magnetic Mxene / CuFeO2 catalyst is applied to activation of persulfate for the first time, and new pollutants such as antibiotics and the like can be selectively oxidized and degraded from the water body by utilizing singlet oxygen generated by activation. By using the method, the effect of removing the typical emerging pollutant-sulfamethoxazole is obvious, and the removal rate can reach 99% or above within 10 minutes. The method has the advantages of high activation efficiency, high efficiency and rapidness in pollutant removal, easiness in catalyst recovery and the like.

Description

Technical field [0001] The present invention belongs to the field of water treatment, and more particularly to methods of activating sulfamer oxazole in sulfa sulfate degradation wastewater by magnetic two - dimensional MXENE / Cufeo2 catalyst. Background technique [0002] Drugs and personal care products (PPCPS) are new types of microbulin, low concentration, diversity, difficult volatile and biodegradable slowness, including various antibiotics, prescription drugs and non-prescription drugs, skin care products, spices and musk, etc. It is currently widely detected in the environment. Sulfonamide is a common antibiotic, mostly used in livestock and aquaculture industry, and its nature is very stable, it is difficult to biodegrapholysis, and it will have a poisonous effect on bacteria, algae, invertebrates and fish in the environmental water body. It is possible to lead to the accumulation of microbial resistance genes, and hazard the human body through the food chain, thereby c...
