| 摘 要： | 近年来汽油添加剂甲基叔丁基醚（MTBE）对环境造成的持久性的危害已越来越受到人们的重视．地下水中MTBE的污染主要是常见于通过地下储藏罐或管道渗漏造成．本文试验研究探讨了O2／H2O2氧化MTBE的降解过程及反应动力学．结果表明：pH值及温度的升高可以明显提高反应速率．MTBE降解过程符合拟一级动力学．当pH为6．5时，速率常数＆为1．20×10^6exp（-40．5／RT）．

| Abstract: | The occurrence of the gasoline additive methyl tert-butyl ether(MTBE) in the environment has received considerable attention.The pollutant is frequently found in the groundwater due to leaking of underground storage tanks or pipelines.This research investigated the reaction kinetics of degradation for the oxidation of MTBE by O3/H2O2.The results showed: pH and temperature increase could increase the reaction rate.And the rate of MTBE degradation exhibited pseudo-first-order behavior.At pH of 6.5,the rate co... |
