摘　　要：通过测量表面张力曲线,计算表面活性剂的相互作用参数βα和βM,从而得出辛基苯酚聚氧乙烯醚和十二烷基苯磺酸钠复配后具有降低表面张力、降低表面张力的效率和形成水溶液混合胶束的协同效应.定量洗油和增溶实验表明:辛基苯酚聚氧乙烯醚和十二烷基苯磺酸钠复配后产生协同效应,并且在洗油能力上表现出了增效效果,但增溶量上没有增效效果,当辛基苯酚聚氧乙烯醚的质量浓度在混合表面活性剂中的比例在0.5～0.8范围内洗油能力最高.The interaction parameters in the monolayer（βα）and the mixed micelles（βM）for each system were determined by surface tension measurement.There were synergisms in ability to reduce the surface tension,the efficiency of reducing surface tension and the formation of mixed micelles between octylpheno1polyoxyethylene and sodium dodecylbenzenesulfonate.Quantitative measurement of washing oil and solubilization showed that there were synergisms between octylpheno1polyoxyethylene and sodium dodecylbenzenesulfonate,and it also showed a synergistic effect in the ability of washing oil,but not in the solubilization.The ability of washing oil was strongest when concentration ratio of octylpheno1polyoxyethylene in the mixed surfactants was between 0.5and 0.8.
