摘要: 利用稳态荧光探针法和电子自旋共振技术测定多烷基苯磺酸钠的临界胶团浓度(cmc)、胶团聚集数(Nagg)、胶团的微极性和微粘度.当干扰基团增加时,烷基苯磺酸钠的临界胶团浓度减少,胶团聚集数减少,胶团微粘度降低,胶团的微极性增强.

关键词: 烷基苯磺酸钠, 聚集行为, 干扰基团, 荧光探针, 电子自旋共振

Abstract: The critical micelle concentration,micelle aggregation number,micelle micropolarity and micelle microviscosity of sodium alkylbenzenesulfonates with the interfering groups have been determined by steady-state fluorescence and electron spin resonance.When the number of the interfering groups increases,the cmc,Nagg and the micelle microviscosity decrease,the micelle micropolarity increases.

Key words: alkylbenzenesulfonate, aggregation, interfering group, fluorescence, electron spin resonance
