摘要
卤代有机物污染问题在世界范围内普遍存在,氧化是一种常见的降解技术,但部分全氯代烃及氟代化合物很难被氧化。水合电子因其极强的还原能力,近年来广泛用于卤代有机物的降解研究,并取得良好的降解和脱卤效果,同时也受到光强、反应介质条件等多种因素的影响,对水合电子的性质、产生方式、卤代有机物降解的影响因素及降解机理进行了介绍,以期为其他相关研究提供借鉴。
The pollution caused by halogenated organic compounds(HOCs) is widespread, oxidation is commonly used for HOCs degradation. However, some HOCs such as perchloro-hydrocarbons and fluorocompounds are hardly oxidized. Recently, as hydrated electron has great reducing capacity, it is widely used in related studies about the degradation of HOCs and excellent degradation and dehalogenation performances were observed. Meanwhile, the degradation process was influenced by various factors, such as light intensity, reaction medium, and so on. The characteristics and generation modes of hydrated electron as well as the influencing factors and mechanism of HOCs degradation were introduced, which can provide reference for related studies.
