| 摘 要： | 通过粘度、电导率、表面张力以及紫外吸收光谱等手段，研究了阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）与水杨酸钠（NaSal）之间的相互作用。结果表明，CTAB与NaSal之间有一定的相互作用，从而使体系表现出较强的粘度行为，并导致其混合溶液的最大紫外吸收峰发生了红移，同时NaSal／CTAB溶液的电导率以及表面张力也发生了一定的变化。

| Abstract: | Interaction between the surfactant CTAB and NaSal were investigated by means of viscosity,electric conductance,surface tension and ultraviolet spectra(UV).Results show that CTAB displays a stronger viscosity behavior in aqueous solution containing the surfactant CTAB,which is due to the molecular interaction of the CTAB and NaSal.In addtion,solution of surfactant the CTAB shows unusual behaviors in electric conductance and ultraviolet spectra(UV) in the presence of NaSal,at the same time,the surface tension and electric conductivity of CTAB/NaSal solution were also changed. |
