摘要
实验就不同浓度的十二烷基三甲基溴化铵（DTAB）水溶液与十六烷之间的界面张力进行定量的测量，分析了表面活性剂DTAB的浓度与水-十六烷界面张力大小之间的关系。并对表面活性剂在油水界面的作用行为进行分析，得到了30℃下水-十六烷体系中DTAB的cmc值，该值显著低于其在水-空气体系中的cmc值。DTAB在该cmc值附近显著降低了水-十六烷界面张力。
Our experiment tests the interfacial tension between different concentration of DTAB and hexa- decane,and also analyzes the relationship between the concentration of surfactant and the water-hexadecane interfacial tension. The paper also analyzes effect of surfactant on the interface of oil-water, and finds the cmc of DTAB in hexadecane-water system under 30℃. The cmc is much lower than that in water-air system,and the interfacial tension of water-hexadecane system was reduced obviously with DTAB.
