摘　　要：氯霉素因抗菌作用良好、生产成本低廉而得到广泛运用,但因为其降解效率较低,在水中检出频率很高,所以对人和环境造成了一定的影响。本文制备的CuFe_(2)O_(4)粉末既可以作为粒子电极,也可以作为活化过硫酸盐(PS)的催化剂,应用在电化学体系(EC)中可催化氧化降解废水中的氯霉素。本文系统研究了操作参数对氯霉素的影响。在CuFe_(2)O_(4)粉末添加量为3.0 g/L,PS浓度为0.004 mol/L,初始pH值为5,恒定电流为0.05 A的曝气状态下,通过180 min处理后氯霉素的去除率为100%。简而言之,EC/CuFe_(2)O_(4)/PS系统可以有效应用于修复被氯霉素污染的地表水和地下水。Chloramphenicol is widely used because of its good antibacterial effect and low production cost.However,owing to its low degradation efficiency,the detection frequency in water is very high,which has a certain impact on people and the environment.In this study,CuFe_(2)O_(4)powder were prepared as both particle electrode and catalyst of activated persulfate(PS),which were used in electrochemical reaction(EC)to degrade chloramphenicol in wastewater.The effects of operation parameters on chloramphenicol were systematically studied.The removal rate of chloramphenicol was 100%when CuFe_(2)O_(4)powder was added 3.0 g/L,PS concentration was 0.004 mol/L,initial pH was 5,constant current was 0.05 A.In short,EC/CuFe_(2)O_(4)/PS system can be effectively used for repairing surface water and ground water polluted by chloramphenicol.
