| 摘 要： | 以经Fe2（SO4）3溶液浸渍改性的活性炭作催化剂、Fenton试剂作氧化剂，采用微波-改性活性炭-Fenton试剂氧化法降解水中的2，4-二氯酚。考察了改性活性炭加入量、H2O2与Fe^2＋摩尔比、Fenton试剂加入量、微波功率和2，4-二氯酚溶液初始pH对2，4-二氯酚降解效果的影响。在改性活性炭加入量1．0g／L、n（H2O2）：n（Fe^2＋）=16．7（H2O2加入量6．0mmol／L、Fe^2＋加入量0．36mmol／L）、Fenton试剂加入量为6．36mmol／L、微波功率600W、微波辐射时间10min、2，4-二氯酚溶液初始pH为6．0的条件下，2，4-二氯酚降解率和TOC去除率分别可达98．7％和84．0％。

| Abstract: | 2,4-dichlophenol in water was degraded by microwave-modified activated carbon-Fenton reagent oxidation with activated carbon modified by dipping in Fe2(SO4)3 solution as catalyst and Fenton reagent as oxidant.The factors affecting the degradation of 2,4-dichlophenol were investigated.The experimental results show that: when modified activated carbon dosage is 1.0 g/L,n(H2O2):n(Fe2+)=16.7(H2O2 dosage 6.0 mmol/L and Fe2+ dosage 0.36 mmol/L),Fenton reagent dosage is 6.36 mmol/L,microwave power is 600 W,microwa... |
