摘　　要：采用Fenton法降解水中布洛芬,考察了H2O2投加量、FeSO.47H2O与H2O2的比值、初始pH、反应时间等因素对布洛芬去除率的影响,通过正交实验确定影响作用大小依次为:[Fe2+]∶[H2O2]的物质的量之比>H2O2的投加量>pH值,最佳的反应工艺条件为:H2O2的投加量为3 mL.L-1,[Fe2+]∶[H2O2]的物质的量之比为1∶10,反应初始pH值为3,反应时间为40 min.在最佳条件下布洛芬的去除率达到86%以上.同时对布洛芬降解反应动力学进行了研究,发现Fenton降解布洛芬符合二级反应动力学规律.The degradation of ibuprofen was investigated by using Fenton method. The effects of different tactors on the removal efficiency of ibuprofen were evaluated. The order of main factors were O O rthogo ptimal nal experiments as follow： the mole ratio of Fe2＋ to H2O2 〉 H2O2 dosage 〉 reaction conditions were as follow ： dosage of H2O2 was 3 mL. L- 1, the mole ratio 1 ： 10, the initial pH was 3 and the reaction time was 40 min. Under such conditions, the ibuprofen was over 86%. The reaction kinetics was also investigated. The degradation of oxidation was accord with the second order kinetics.
