  • 摘要: 采用Fenton法降解水中布洛芬,考察了H2O2投加量、FeSO4·7H2O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.
    Abstract: The degradation of ibuprofen was investigated by using Fenton method. The effects of different factors on the removal efficiency of ibuprofen were evaluated. The order of main factors were determined through orthogonal experiments as follow: the mole ratio of Fe2+ to H2O2 ＞ H2O2 dosage＞ the initial pH. The optimal reaction conditions were as follow: dosage of H2O2 was 3 mL·L-1, the mole ratio of Fe2+ to H2O2 was 1∶10, the initial pH was 3 and the reaction time was 40 min. Under such conditions, the removal efficiency of ibuprofen was over 86%. The reaction kinetics was also investigated. The degradation of ibuprofen by Fenton oxidation was accord with the second order kinetics.
