摘　　要：利用溶剂热法合成CoFe_(2)O_(4)@MIL-100(Fe)复合催化剂,并采用扫描电镜、红外光谱等对其进行表征。以CoFe_(2)O_(4)@MIL-100(Fe)为催化剂,活化Oxone降解金橙Ⅱ,考察了MOFs包覆情况、污染物初始浓度、pH、氧化剂浓度、催化剂投加量等因素对其降解率的影响。加入CoFe_(2)O_(4)@MIL-100(Fe)、增加氧化剂的用量、保持弱酸性条件均可以显著提高金橙Ⅱ的降解率。In this study,CoFe_(2)O_(4)@MIL-100(Fe)was synthesized by solvothermal method.The synthetic nanoparticles were characterized by using scanning electron Microscope(SEM)and Fourier transform infrared spectra(FTIR).Effects of MOFs addition,pollutant initial concentration,pH,Oxone concentration,and on the degradation rate of acid orange Ⅱ by Oxone are examined in batch experiments.Results indicated that the presence of CoFe_(2)O_(4)@MIL-100(Fe)successfully accelerates the degradation rate of acid orange Ⅱ.The degradation rate increased as the initial Oxone concentration increased;the degradation rate was low at neutral and alkaline conditions while acidic conditions was higher.
