摘　　要：为探究生物炭负载铁酸铜去除水中抗生素环丙沙星的机制及影响因素,采用商业生物炭颗粒为载体制备双金属类芬顿催化剂。XRD和SEM分析结果表明,采用共沉淀法高效合成铁酸铜双金属类芬顿催化剂,生物炭作为载体分散了铁酸铜催化剂,可有效提高铁酸铜在连续流中的保留率,避免催化剂的流失。催化剂材料对环丙沙星去除效果的研究表明,负载铁酸铜的生物炭催化剂材料对环丙沙星的去除率高达100%,其催化性能在pH值为2~10范围内没有显著变化。电子顺磁共振波谱(EPR)研究表明,负载铁酸铜的生物炭催化剂材料活化H_(2)O_(2)降解环丙沙星的主要活性物种是羟基自由基。To investigate the mechanism and influencing factors of the removal of antibiotic ciprofloxacin from water by biochar-loaded CuFe2O4,bimetallic Fenton catalysts were prepared using commercial biochar particles as carries.XRD and SEM characterization showed that the CuFe2O4 bimetallic Fenton catalyst was efficiently synthesized by co-precipitation method,The biochar was used as a carrier to disperse the copper ferrite catalyst,which effectively improved the retention rate of CuFe2O4 in the continuous flow and avoided the loss of catalyst.The experimental research on the effect of catalyst materials on the removal of ciprofloxacin showed that the biochar catalyst material loaded with CuFe2O4 could achieve 100%removal of ciprofloxacin and its catalytic performance did not change obviously when the pH value was in the range of 2-10.The EPR studies showed that the main active species of the biochar catalyst material loaded with CuFe2O4 to activate H_(2)O_(2) for the degradation of ciprofloxacin were hydroxyl radicals.
