摘要
烷基苯磺酸钠作为一种常用的表面活性剂广泛应用于洗涤行业。支链烷基苯磺酸钠(ABS)由于能引起细胞膜结构的破坏和功能丧失,且难以生物降解,已逐渐退出洗涤领域。但是,由于ABS拥有较高的发泡力、润湿力,其相应功能远高于直链烷基苯磺酸钠(LAS),故ABS仍应用于农药乳化剂和油田助剂等领域。本文就ABS及其常见表面活性剂的应用、毒性及其降解处理方法等进行系统的论述,并深入探讨ABS回收利用的方案及可能性,为其资源化应用提供理论依据。
Sodium alkyl benzene sulfonate as a kind of common surfactants is widely used in detergent industry,because of the significant decrease of water's surface tension.However,sodium dodecylbenzene sulfonate(ABS)can cause destruction and dysfunction of cell membrane structure,and it is difficult to biodegrade,which gradually withdraws from the field of washing.Besides,because of the stronger foaming power and the higher wetting force for ABS than that of linear alkylbenzene sulfonate(LAS),it is also used in pesticide emulsifier and oil additives and other fields.The application,toxicity and treatment methods of the degradation of surfactants were reviewed,and the recycling of ABS was discussed.
