摘要 混合表面活性剂在非极性溶剂中的聚集行为刘道军马季铭*程虎民赵振国(北京大学化学系北京100871)关键词混合表面活性剂,非极性溶剂,聚集行为,碘光谱法,水增溶,临界胶束浓度1997-05-26收稿,1997-09-02修回国家自然科学基金资助课题表面... The aggregation behaviour of mixed surfactants, sodium bis(2ethylhexyl) sulfosuccinate and Brij30, in nheptane has been investigated by iodine spectrometric method. The results showed that the CMC of the mixed surfactants firstly decreased and then increased with the increase of the proportion of nonionic surfactant Brij30 due to electric interaction and geometry of the surfactants. The water solubilization investigation indicated that at lower surfactant concentration the solubilizing capacity of the mixed reverse micelles firstly increased and then decreased with the increase of the proportion of Brij30. The difference of CMC values determined by iodine spectrometric method and water solubilization has been discussed.
