摘要
利用滴体积法研究了40℃时阴离子Gemini(C6-G)与CTAB复配体系的相互作用。结果表明:C6-G/CTAB复配体系在配比为0.3∶0.7时cmc达小值1.56×10-5mol/L,配比为0.5∶0.5时γcmc达小值27.3 mN/m;C6-G/CTAB复配体系在降低表面张力的效率和形成胶束的能力方面存在协同效应;配比为0.7∶0.3时在降低表面张力的能力方面存在协同效应。
Interaction of mixed system of novel anionic Gemini surfactant （C6 - G） and cetyltrimethylammonium bromide （CTAB） were studied by drop volume method at 40 ℃. The results showed thatcmc of the C6 - G/CTAB mixture reached the minimum of 1. 56 × 10^ -5 moVL at the ratio of 0.3 ： 0.7, and the minimum γcmc was 27. 3 mN/m at the ratio of 0. 5 ： 0.5. All the C6 - G/CTAB mixtures exhibited synergism in both surface tension reduction efficiency and mixed micelle formation and exhibited synergism in surface tension reduction effectiveness at the ratio of 0. 7 ： 0. 3.
