摘要
The removal effect of Fenton’s oxidation treatment of benzene, toluene, ethyl benzene, and xylenes (BTEX) in groundwater was investigated. The results show that Fenton’s reagent suggested a strong ability to oxidize BTEX. While H2O2 /BTEX(molar ratio) = 5 and 10, H2O2 /Fe(II) (molar ratio) = 4 and 8 were best for oxidizing BTEX. The removal rate was over 80%.While H2O2 /BTEX (molar ratio) = 20, Fenton’s reagent suggested an effectively oxidation and there was little impact of H2O2 /Fe (II) on Fenton’s treatment effect. The removal rate was 97% ～ 100% while H2O2 /Fe(II) = 10. The whole Fenton system displayed a strong oxide environment and pH reduced from 6 ～ 7 to around 3 immediately.
