| 摘 要： | 通过测定苄泽类非离子型表面活性剂Brij58、Brij76、Brij78与阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)、阴离子表面活性剂十二烷基硫酸钠(SDS)复配体系的表面张力,研究了复配体系的形成胶束能力、降低表面张力效率、降低表面张力能力3种增效作用,并结合复配体系中表面活性剂分子间的相互作用参数进行了深入的讨论。研究结果表明,与阳离子表面活性剂复配时,Brij76/CTAB体系增效作用最强;与阴离子表面活性剂复配时,Brij58/SDS复配体系增效作用最强,而且苄泽类非离子型表面活性剂与阴离子表面活性剂复配增效作用更加显著。

| Abstract: | The surface tension of the mixed systems of Brijs and hexadecyltrimethylammonium bromide (CTAB),Brijs andsodium dodecyl sulfate ( SDS) were measured respectively. The ability of forming micelle,the efficiency and the ability ofreducing surface tension had been investigated. And the relationship between molecular interaction parameter and the ratio ofsurfactants in mixed solutions was discussed. It was found that the synergy of Brij76 /CTAB and Brij58/SDS showed a maximumin each system and the synergy betwee... |
