摘要
制备了十六烷基三甲基溴化铵 /正丁醇 /正庚烷 /水四组分体系的相图 .讨论了体系中助表面活性剂与表面活性剂的质量比km 对形成微乳状液单相区域大小的影响 .以二茂铁为电活性探针用半微分电分析法测定系列微乳样品的表观扩散系数Dapp,从表观扩散系数Dapp随含水量Φw 的变化确定微乳液的微结构和结构转变 .
Pseudo-ternary phase diagrams in four-component system of cetyltrimethylammonium bromide/n-butanol/n-heptane/water (CTAB/n-C4H9OH/n-C7H16/H2O) are presented. The influence of cosurfactant-to-surfactant mass ratio, k(m) = W(C4H9OH)/W(CTAB), on the size of the microemulsion. region in the title system is discussed. The apparent diffusion coefficients D-app, of several microemulsion samples were measured by using ferrocene (Fc) as the electroactive probe by semidifferential electroanalysis. The microstructure and the structural conversion of the microemulsion has been determined from the water content dependence of the apparent diffusion coefficients in one-phase microemulsion region. The electrical conductivity datum supported the results of the semidifferential electroanalytical measurement.
