双子阳离子表面活性剂胶束聚集数的测定
DETERMINATION OF THE MICELLE AGGREGATION NUMBER OF GEMINI CATIONIC SURFACTANTS
摘要
Abstract
The micelle aggregation number (Nagg) of Gemini cationic surfactants N, N’-alkyl-2-hydroxyl-N, N, N’, N’-tetramethyl diamonium dichloride (abbreviated as GCnNCl2, n =12, 14, 16), was determined by steady-state fluorescence measurements in the temperature range of 20~35 oC, the pyrene as the fluorescence probe and diphenyl ketone as the quencher. The results indicated that Nagg of GCnNCl2 increases linearly with the increasing surfactant concentration within a certain concentration range, but the micropolarity of pyrene decreases with the increasing concentration.关键词
