摘要 研究了不同温度下1,4-丁二醇双子琥珀酸二仲辛酯磺酸钠(GSS 471)和异辛基酚聚氧乙烯醚(TX-100)复配物(GSS 471/TX-100)在水中的表面行为、在表面吸附层和混合胶束中的相互作用以及热力学行为,对混合体系中各组分在表面吸附层和胶束中的组成、相互作用参数及热力学参数等进行了分析比较。研究结果表明,温度对复配溶液的临界胶束浓度(cmc12)有较大影响,cmc12均随温度的升高而先增大后减小,而纯组分溶液的临界胶束浓度(cmc)呈单调下降趋势。低温(20℃)有利于在形成胶束能力上以及在表面吸附层中产生正加和增效。胶束中富含TX-100分子,而大部分GSS 471则以游离的形式存在于溶液中。 The surface behavior in water of Compound GSS 471/TX-100 prepared with 1,4-butanediol gemini di-sec-dioctyl sulfosuccinate sodium ( GSS471) and isooetyl phenol polyethoxylate (TX-100) and the interaction between GSS 471 and TX-100 and the thermodynamic behavior of the compound in surface adsorption layer and mixed micelle at different temperatures were studied, and the compositions of the components of the mixed system in surface adsorption layer and micelle, their interaction parameters and the thermodynamic parameters of compound, etc. were analyzed and compared. The results of research have shown that the temperature has significant effect on the critical micelle concentration of the compound solution ( cmc12 ) and cmc12 increases first and then decreases as the rise of temperature and that the critical micelle concentration of pure component solution (cmc) decreases monotonically as the rise of temperature. Low temperature (20℃) is favorable for the creation of plus and increase efficiency for the formation of micelle capacity and in the surface adsorption layer. The micelle is rich in TX-100 molecules while a majority of GSS 471 molecules are present in the solution in free state.
