Fenton和类Fenton氧化处理地下水中BTEX及其动力学
Treatment of BTEX in groundwater by Fenton's and Fenton-like oxidation reaction and the kinetics
摘要
Abstract
The removal efficiency and the kinetics of oxidation treatment of benzene, toluene, ethyl benzene and xylenes(BTEX) contaminated groundwater by Fenton's reagent and Fenton-like reagent were investigated and compared in the groundwater. The results indicated that Fenton's reagent has a better removal effect on BTEX than Fenton-like reagent. Moreover,both Fenton and Fenton-like reaction systems were in strong oxidation environments and the pH maintained around 3 during the whole processes. The oxidation processes of BTEX by Fenton’s reagent and Fenton-like reagent both followed the second order reaction kinetic equation: 1/C = kt + 1/C0. The average half-lives of BTEX treated by Fenton's reagent and Fenton-like reagent were 0.057 h and 0.642 h respectively. The order of the rate constants during the oxidation processes was ethyl benzene ＞ xylenes ＞ toluene ＞ benzene.关键词
