| 摘 要： | 用电导法研究了十六烷基三甲基溴化铵 (CTMAB)与羟丙基 β 环糊精 (HP β CD)及 β 环糊精 (β CD)混合体系的电导行为。结果表明 ,由于CTMAB与HP β CD或 β CD间形成了包合物 ,使体系电导率增加的幅度减缓。当体系中HP β CD或 β CD的浓度增加时 ,CTMAB的临界胶束浓度 (CMC)增加 ,即转折点后移 ,且HP β CD对CTMAB的CMC转折点后移的影响较 β CD明显

| Abstract: | The conductivities of mixed systems of hydroxypropyl-β-cyclodextrin(HP-β-CD)or β-cyclodextrin(β-CD)with cetyltrimethylammonium bromide(CTMAB) were studied.The results showed that the conductivities of mixed systems of HP-β-CD or β-CD with CTMAB increase more slowly than that of CTMAB only,due to formation of inclusion complexes of HP-β-CD or β-CD with CTMAB. The critical micelle concentration(CMC) of CTMAB is also increased by increasing the concentration of HP-β-CD or β-CD,and it can be found that the effect of HP-β-CD on CMC of CTMAB is more obvious than that of β-CD. |
