Mixed micelles formed with cetyl pyridinium chloride (CPC), cetyl trimethylammonium bromide (CTAB), and polyoxyethylene (10) cetyl ether (Brij-56) mixed in different combinations in aqueous medium have been studied in detail by tensiometric, conductometric, calorimetric, spectrophotometric, and fluorimetric techniques. Different physicochemical properties such as critical micellar concentration (cmc), micellar dissociation, energetic parameters (free energy, enthalpy, and entropy) of micellization, interfacial adsorption, and micellar aggregation number have been determined. The results have been analyzed in terms of the equations of Clint, Motomura, Rosen, Rubingh, Blankschtein et al., and Rubingh and Holland for justification of the experimental cmc, determination of micellar composition parameters, quantification of interaction among the mixed micelle components, and estimation of their activity coefficients.
通过张力测定法、电导测定法、量热法、分光光度法和荧光测定法，对在水介质中以不同组合混合的十六烷基吡啶氯化物（CPC）、十六烷基三甲基溴化铵（CTAB）和聚氧乙烯（10）十六烷基醚（Brij-56）形成的混合胶束进行了详细研究。已测定了不同的物理化学性质，如临界胶束浓度（cmc）、胶束解离、胶束化的能量参数（自由能、焓和熵）、界面吸附和胶束聚集数。根据克林特、本村、罗森、鲁宾、布兰克施泰因等人以及鲁宾和霍兰德的方程对结果进行了分析，以验证实验cmc、确定胶束组成参数、量化混合胶束组分之间的相互作用以及估计它们的活度系数。
