| 摘 要： | 研究了椰油酰胺丙基甜菜碱(CAB)/十二烷基苯磺酸钠(LAS)复配体系形成临界胶束浓度的变化规律和不同价态无机盐对复配体系临界胶束浓度、泡沫性能的影响.结果表明:复配体系在降低临界胶束浓度能力方面可以产生协同增效作用,在LAS与CAB之比为5∶5~2∶8时,协同效应显著,其中LAS与CAB的比为3∶7时,为体系最佳复配比.低浓度的无机盐能使复配体系的临界胶束浓度下降,发泡力上升.无机盐浓度过大时,表面活性剂的稳泡性和发泡力却大幅度下降.不同价态的无机盐对表面活性剂混合体系的泡沫性能影响规律是Na+

| Abstract: | The formation of ability of cmc,the influence of different inorganic salt on cmc and foamability of the mixed system of zwitterionic/ anionic surfactants(CAB/LAS) has been investigated.It is found that when the mole ratio of LAS to CAB is about 5∶5～2∶8,especially when the ratio of 3∶7,the surface activity shows a maximum.The experiment indicated that the foamability was enhanced and the cmc value of the mixed system was reduced with the increase of inorganic salt concentration,but the foamability was weakened when the salts were applied at higher concentration and different electric charge number of the inorganic salt has different foamability effect on the mixed system: Na+
