采用高级氧化法修复敌百虫污染的土壤，考察了 pH 值、Fe2＋、H2O2、敌百虫初始浓度等因素对土壤中敌百虫去除效率的影响。结果表明，芬顿高级氧化法能有效地降解土壤中的敌百虫，最佳条件为水土比2∶1，初始 pH 值3．0， H2O2/Fe2＋的物质的量比25∶1。采用间歇式加入过氧化氢的操作方法，在污染土壤中加入 Fenton 试剂，敌百虫的降解率达到可达99．3%，并且其降解速率符合一级反应动力学规律。
採用高級氧化法脩複敵百蟲汙染的土壤，攷察瞭 pH 值、Fe2＋、H2O2、敵百蟲初始濃度等因素對土壤中敵百蟲去除效率的影響。結果錶明，芬頓高級氧化法能有效地降解土壤中的敵百蟲，最佳條件為水土比2∶1，初始 pH 值3．0， H2O2/Fe2＋的物質的量比25∶1。採用間歇式加入過氧化氫的操作方法，在汙染土壤中加入 Fenton 試劑，敵百蟲的降解率達到可達99．3%，併且其降解速率符閤一級反應動力學規律。

Fenton’s reagent was used for remediation of trichlorphon-contaminated soils. The effects of the con-centrations of Fe2+,H2O2, trichlorphon and pH on the remediation efficiency of trichlorphon in soil were investi-gated. The results show that the Fenton oxidation process has high degradation efficiency for trichlorphon in con-taminated soil. The optimal operating conditions are as follows: the liquid-to-soil ratio was 2∶1,pH was 3.0,the H2O2-to-Fe2+ratio(molar concentration) was 25∶1. Adding Fenton reagent and hydrogen peroxide intermittently in the contaminated soil, the degradation ratio of trichlorphon can reach 99.3%, and it follows the first-order kinet-ics.
