摘要 为了深入了解阳离子表面活性剂溶液在复杂体系中的物理化学性质,以十六烷基三甲基氯化铵(CTAC)和十六烷基三甲基溴化铵(CTAB)为模型,通过电导法和表面张力法研究其在水相体系中的聚集行为。测定两种表面活性剂的临界胶束浓度CMC、胶束离解度β、胶束聚集数n和表面过剩吸附量Γs。由CMC与温度T的关系,应用准相分离模型计算了胶束化热力学参数ΔmicG0、ΔmicH0和ΔmicS0,结果表明ΔmicG0为负值,而且随温度变化很小,ΔmicH0的值相对于TΔmicS0来说小得多,表明胶束化过程为熵驱动过程。 To probe into the thermodynamic characteristics of the cationic surfactants, this paper presents a laboratory experiment conducted to investigate the aggregation behavior of hexadecyltrimethylammonium chloride (CTAC) and hexadecyltrimethylammonium bromide (CTAB) in water by electrical conductivity and surface tension in terms of critical micelle concentration(CMC), degree of counter ion dissociation(β),aggregation number(n)and surface excess concentration (Гs). Calculation of the thermodynamic parameters by...
