摘要/Abstract

摘要： 以芘为荧光探针、二苯甲酮为猝灭剂,用稳态荧光探针法测定了合成的3种高纯的烷基苄基聚氧乙烯醚丙烷磺酸钠的临界胶束浓度、不同表面活性剂浓度下的胶团聚集数和胶团微极性.研究了链长变化对烷基苄基聚氧乙烯醚丙烷磺酸钠聚集性质的影响.考察了胶团聚集数的浓度效应,并由胶团聚集数与表面活性剂浓度关系方程外推求得了它们各自的临界胶束聚集数.

关键词: 稳态荧光猝灭, 临界胶束浓度, 胶团聚集数, 胶团微极性, 烷基苄基均质聚氧乙烯醚丙烷磺酸钠

Abstract: Critical micelle concentration(CMC),micelle aggregation numbers(N) at different surfactant concentrations(c) and micellar micropolarity of three sodium alkyl-benzyl homogeneous polyoxyethlenated propane sulfonates(ABEPS) were determined by steady-state fluorescence probe method in which pyrene was used as fluorescence probe and benzophenone was used as quencher.The influence of the change of alkyl chain of ABEPS on the aggregation properties was studied.The varieties of N with the c of ABEPS were also discussed,and the critical micelle aggregation numbers of ABEPS were obtained from the experimental equation of N versus c.

Key words: Steady-state fluorescence quenching, critical micelle concentration, micelle aggregation number, micellar micropolarity, sodium alkyl-benzyl homogeneous polyoxyethylenated propane sulfonate
