摘　　要：为了改进Fenton氧化法的缺陷,采用浸渍法制备了负载型双金属Co-Fe/Al_2O_3催化剂,探究了在非均相催化条件下活化过氧化氢(H_2O_2)与过硫酸氢钾(PMS)降解罗丹明B(Rh B)的性能,并分别考察了处理方法、反应温度、反应时间对罗丹明B降解率的影响。结果表明,在Co-Fe/Al_2O_3催化剂、H_2O_2和PMS的共同作用下,罗丹明B的氧化降解率随着反应温度和反应时间的增加而提高。In order to improve the defects of Fenton oxidation method,we have prepared supported bimetallic Co-Fe/Al2O3 catalyst by impregnation method. The catalytic performance of Co-Fe/Al2O3 was studied as a heterogeneous catalyst for degradation of Rhodamine B（ RhB） by activating hydrogen peroxide（ H2O2） and peroxymomsulfate（ PMS）. The effects of treatment methods,reaction temperature,and reaction time on the oxidative degradation were also investigated. The results showed that the oxidation degradation rate of rhodamine B increased with the increase of reaction temperature and reaction time under the combined action of Co-Fe/Al2O3 catalyst,H2O2 and PMS.
