Fenton试剂的反应机理及动力学研究进展

摘要

Fenton试剂是由H.J.H.Fenton在120年前首次发现的,其通过Fe2+与H2O2反应,生产具有强氧化性的活性物种,将有机分子矿化为CO2和H2O,广泛应用于污水处理、地表水修复等领域,是一种具有广阔应用前景的污染物治理技术.关于其作用机理,目前尚未形成统一看法,总结了Fenton试剂在机理和动力学方面的研究成果,并对不同机理进行了评价,最后对该体系的理论研究进行了展望.%Fenton reagent was discovered the first time by H.J.H.Fenton 120 years ago. Through Fe2+and H2O2 reac-tion,it can produce active species with strong oxidability,and mineralize organic molecules into CO2 and H2O. Being a kind of pollutant treatment technology having wide application prospect ,it can widely be applied to wastewater treatment and surface-water remediation fields. However,up to now,no coincident opinion has been formed. The re-search achievements on mechanisms and kinetics of Fenton reagent are summarized ,and different mechanisms are evaluated in this paper. At the end,theoretical research of this system is looked forward.
