有机污染物光降解过程中活性中间体的研究进展
|
摘要
对水环境中有机污染物的光降解机理以及围绕反应过程中活性中间体展开的定量研究进行了综述。光降解是水体中难以生物降解的持久性有毒污染物迁移转化的重要途径。主要介绍了水环境中有机污染物的光降解过程所涉及的主要活性中间体,包括单线态氧(~1O_2)、羟基自由基(·OH)和有机物的三重激发态(~3OM~*),并对其如何定量分析、具体的促进作用和机理及其广泛应用进行了阐述。
The mechanism of photodegradation of persistent organic pollutants in aqueous solution including the quantitative studies expanded around the reactive intermediates in the reaction was reviewed. Photodegradation was an important pathway for the transformation of persistent toxic pollutants that are poorly biodegradable in aquatic systems. The main active intermediates involved in the photodegradation process of organic pollutants in water environment were mainly introduced, including singlet oxygen(~1O_2), hydroxyl radical(·OH) and triplet excited state of organic compounds(~3OM~*). The quantitative analysis of these active intermediates, promotion effect, forming mechanism and its wide application were elaborated specifically.
