表面活性剂降解研究进展

The Development of Study on Degradation of Surfactants

简述了表面活性剂对环境的影响及其降解的发展概况。着重讨论了表面活性剂的各种生物降解的研究方法和特点 ,降解动力学 ,结构与降解性能间的关系 ,影响降解的环境因素及直链烷基苯磺酸盐 (LAS)、烷基硫酸盐(AS)等几类常见表面活性剂的生物降解机理。并对近年发展起来的表面活性剂光催化降解的研究方法。

The developments about the influence of surfactants on environment and about the degradation of surfactants have been briefly reviewed.Some researching methods with their each relevant peculiarities and the kinetics about biodegradation,the relation between structure and biodegradability,and the environmental factors acting on the degradation of surfactants are all studied.The appropriate biodegradation mechanisms for some surfactants such as linear alkylbenzenesulfonate(LAS),alkylsulfonate(AS)are illustrated.And the similar progresses for photodegradation methods of surfactants developed in recents year are also briefly introduced.
