摘　　要：研究了铁柱撑膨润土/UV/Fenton多相催化氧化降解五氯苯酚(PCP)的行为,探讨了反应过程中溶液初始pH、铁柱撑膨润土投加量、H2O2浓度等因素对光催化降解的影响。研究表明:在pH=9.0、铁柱撑膨润土投加质量浓度为50.0 mg/L、H2O2浓度为0.6 mmol/L的条件下,反应80 min后,铁离子质量浓度<0.5 mg/L,五氯苯酚降解率高达98%。实验结果表明,铁柱撑膨润土/UV/Fenton工艺对PCP具有良好的降解效果。The heterogeneous catalysis oxidative degrada UV/Fenton process has been studied. The effects of tion of pentachlorophenate （PCP） by Fe-pillared bentonite/ initial pH of the solution,Fe-pillared bentonite dosage, concentration of H2O2, etc. on the degradation of PCP are investigated. The results show that the degradation rate of PCP is as high as 98% under the following conditions ： the solution pH=9.0, Fe-pillared bentonite dosage=50.0 mg/L, H2O2 concentration=0.6 mmol/L, reaction time=80 min, and the mass concentration of Fe ions is lower than 0.5 mg/L. The experiment proves that Fe-pillared bentonite/UV/Fenton has good effects for removing PCP from water.
