Aqueous solutions of the cationic surfactant, hexadecyl-trimethyl ammonium bromide (CTAB), and the anionic surfactant, sodium dodecylsulfate (SDS) were used as mobile phase in HPLC to study the micellar chromatographic retention mechanism of seven amines and weak organic acids with various distribution coefficients and to study the influence of different pH values mobile phase on the solute retention. An exponential model equation for micellar chromatographic retention mechanism was put forward, which gives a reasonable explanation of the effects of electrostatic interaction and hydrophobic interaction between the solute and the three phases (micelle phase, surfactant modified stationary phase and bulk water phase). This equation can be used to estimate the micellar chromatographic retention pattern of the solute.
阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）和阴离子表面活性剂十二烷基硫酸钠（SDS）的水溶液被用作高效液相色谱（HPLC）的流动相，以研究七种具有不同分配系数的胺类和弱酸的胶束色谱保留机理，并研究不同pH值流动相对溶质保留的影响。提出了胶束色谱保留机理的指数模型方程，该方程对溶质与三相（胶束相、表面活性剂改性固定相和本体水相）之间的静电相互作用和疏水相互作用的影响给出了合理的解释。该方程可用于估计溶质的胶束色谱保留模式。
