| 摘 要： | 采用微波/Fenton氧化法降解水中阴离子表面活性剂十二烷基苯磺酸钠(SDBS).比较了微波辐射、Fenton氧化和微波/Fenton氧化3种方法对SDBS的降解效果;考察了H2O2与Fe2+的摩尔比、Fenton试剂投加量、微波功率、溶液pH、反应时间等因素对SDBS降解效果的影响.结果表明,微波辐射可以强化Fenton试剂对SDBS的氧化作用,明显提高SDBS的降解效率,显著缩短反应时间,并能促进SDBS的矿质化,提高TOC去除率;微波辐射与Fenton氧化对SDBS的矿质化具有明显的协同效应.微波/Fenton氧化法降解SDBS的最佳工艺条件为:pH为3,n(H2O2):n(Fe2+)为195,Fenton试剂投加量为140mmol·L-1,微波功率为500W,反应时间为10min.在此工艺条件下,SDBS和TOC去除率分别可达99%和68%.

| Abstract: | Sodium dodecylbenzene-sulphonate(SDBS)in water was degraded by microwave/Fenton oxidation.The degradation efficiencies of SDBS degraded by microwave irradiation,Fenton oxidation and microwave/Fenton oxidation were compared.The effects of reaction conditions,such as n(H2O2):n(Fe2+) ratio,dosage of Fenton reagent,microwave power,pH value and reaction time on degradation efficiency of SDBS were investigated.The results showed that microwave irradiation can not only enhance the oxidation of SDBS so as to increa... |
