摘要
针对粉末状类Fenton催化剂难以回收再利用的难题,采用煅烧法制备球形铁铜双金属复合催化剂,优化了催化剂制备条件(成分配比、煅烧条件和氮气流量),表征了催化剂的表面形态,考查了阿莫西林降解动力学,探讨了催化剂催化机理,并利用以该催化剂为核心的类Fenton催化体系处理阿莫西林模拟废水。反应在最优条件下阿莫西林去除率可达到99.9%。
Aiming at the problem that powdered Fenton catalysts are difficult to recycle and reuse,a spherical Fe-Cu bimetallic composite catalyst was prepared by calcination method.The catalyst preparation conditions(composition ratio,calcination conditions and nitrogen flow)were optimized,the surface morphology of the prepared catalyst was characterized,the degradation kinetics of amoxicillin were investigated,and the catalytic mechanism of catalysts was discussed.The Fenton-like catalytic system driven by the catalyst was used to treat amoxicillin simulated wastewater.The removal rate of amoxicillin can reach 99.9% under optimal conditions.
