摘  要:研究了糖苷基季铵盐(CAPG)与α-烯基磺酸钠(AOS)复配体系的稳定性以及在表面和溶液中的相互作用。结果表明,复配体系具有很好的稳定性,在形成胶束的能力、降低表面张力的效能及效率方面均有显著的提高,当n(CAPG)∶n(AOS)=1∶1时增效作用最为明显,其cmcT(临界胶束浓度)、γcmc(临界胶束浓度时的表面张力)和cπ=40(表面张力为40mN.m-1时表面活性剂的总浓度)分别为4.4×10-5mol.L-1,24.9mN.m-1和1.7×10-5mol.L-1,混合表面活性剂在表面和胶束中的相互作用参数βσ和βm分别为-15.93和-14.29,表现出很好的协同效应。Stability and interactions of blend systems of glucosidyl quaternary ammonium salt (CAPG) and alpha- olefin sulfonate (AOS) were studied. Results showed that blend systems not only display good stability, but also significant improvement for efficacy and efficiency of micelle formation and surface tension lowering. At condition of n (CAPG) : n ( AOS ) =1:1, the synergic effect is at the highest and the critical micelle concentration (cmcτ) ,the surface tension(γcmc) and the overall concentration when surface tension of aqueous solution reduced 40mN·m^-1(Cπ=40) is 4.4×10^-5mol·L^-1,24.9mN·m^-1 and 1.7×10^-5mol·L^-1 respectively. The molecular interaction parameter βσ, and βm achieves -15.93 and -14.29 respectively ,which also reflects good synergism.
