| 摘 要： | 采用活性炭-Fenton组合方法催化氧化去除水中的邻苯二甲酸酯(PAEs),研究了H2O2、Fe2+-、H2O2/Fe2+-及活性炭的用量、pH值、反应时间以及PAEs的初始浓度等对水中PAEs去除率的影响.结果表明,在Fenton试剂与活性炭的协同作用下,对PAEs具有较好的去除效果.PAEs水溶液(DMP、DEP、DBP、DOP各为12 mg·L-1),经活性炭-Fenton法处理15 h后,PAEs的平均去除率可达到99.1%.

| Abstract: | Removal of PAEs by combined process of activated carbon-Fenton was investigated. Factors associated with PAEs removal ratio following amount of activated carbon, dosages of oxidant, catalyst, initial concentration of PAEs, pH value and reaction time were studied. Results showed that high purification performance could be obtained by the synergetic effect of Fenton reagent and activated carbon. Average removal ratio of PAEs was 99.1% for the solution containing 12 mg x L(-1) DMP, DEP, DBP, DOP respectively by the activated carbon-Fenton process for 15 h. |
