| 摘 要： | 全氟辛酸(PFOA)因其在环境介质中的稳定性、持久性和生物累积性,常规方法很难将其降解,或必须付出昂贵的代价.近几年,一些研究者利用紫外光化学降解环境介质中的PFOA,显示出了优良的应用前景.本文结合国内外研究者近年来的工作,介绍了紫外光化学降解PFOA的原理与特性,对各体系中关键介质的作用与机理进行了讨论,针对紫外光化学降解PFOA存在的问题提出了见解,并对该领域研究的趋势进行了展望.

| Abstract: | The persistence and bioaccumulative properties of perfluorooctanic acid(PFOA) make it difficult to degrade via conventional methods.In recent years,some good progress has been made on photochemical degradation of PFOA using UV irradiation.This paper reviews the existing literature on the brief information and characteristics of UV photochemical degradation,with particular focus on the detailed mechanisms of the key media involved in these processes.The current status of the field and recommendations for fur... |
