摘要
本文研究了阴离子表面活性剂十二烷基磺酸钠(SAS)分别与阴离子表面活性剂十二烷基硫酸钠(SDS)及阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)复配体系的胶团。结果表明:任何比例的两复配体系均形成非理想混合胶团;对于SAS/SDS体系高活性组分在胶团中所占的摩尔分数高于它在体系中的摩尔分数;而在体系SAS/CTAB中,两组分在胶团中的摩尔比却趋近于1:1,并不与它们在体系中的摩尔比相对应;复配体系SAS/SDS和SAS/CTAB的β~M值分别为-2.94和-26.47,表明前者偏离理想混合不大,而后者则偏离较远,但两体系在形成胶团能力方面均出现增效作用。
The micelle of mixing system SAS/SDS and SAS/CTAB is studied in this paper. The result is that nonideal mixing micelle is formed in this system at any ratio. The mole fraction of higher active component is more than one of lower active component in the micelle of the SAS/SDS system. And the ratio of two components in the micelle approaches one to one in the SAS/CTAB system. The βM value is respectively equal to - 2. 94 and-26. 47 in the SAS/SDS and SAS/CTAB system. That means the synergism on mixed mieelle formation is existed in the two systems.
