中文摘要：

采用荧光分光光度法和Zeta电位法考察了系列Gemini双季铵盐表面活性剂与阴离子表面活性剂十二烷基苯磺酸钠（SDBS）和十二烷基磺酸钠（SDS）的复配效果。结果表明，Gemini双季铵盐表面活性剂疏水链和连接基越长，cme越小，且疏水链长度对表面活性剂性能的影响较大；Gemini双季铵盐表面活性剂的加入可显著提高阴离子表面活性剂SDBS和SDS的表面活性，当Gemini双季铵盐表面活性剂与SDBS或SDS的摩尔比为3：7时，复配体系的eme最小，且与SDS复配体系的性能优于与SDBS的复配体系。

英文摘要：

Synergistic effect of bis -quaternary ammonium salt Gemini surfactant blended separately with sodium dodecylbenzene sulfonate （SDBS） and sodium dodecane sulfonate （SDS） were investigated by fluorospectrophotometry and Zeta potential method. Results showed that the longer the hydrophobic chains and the space group of the bis - quaternary ammonium salt Gemini surfactant, the lower the cmc value ; while length of the hydrophobic chain displays bigger effect on performance of the surfactant. Addition of bis - quaternary ammonium salt Gemini surfactant can significantly increase the surface activity of anionic surfactants such as SDBS and SDS. When molar ratio of the bis - quaternary ammonium salt Gemini surfactant to SDBS （SDS） is 3： 7, cmc of the blended surfactant achieves the least. Synergistic effect of the bis - quaternary ammonium salt Gemini surfactant with SDS is better than that with SDBS.
