摘　　要： 本文研究三个价型六种盐对C_8-卵磷脂微团溶液的液-液相分离调控的规律,测定出各种加盐溶液的两相共存曲线,获得了各系统相变临界温度T_c随盐类型和盐离子强度变化的关系。用我们先前导出的关于盐对该微团溶液相变影响关系的方程式为T_c=T^0_c-A_1[I]~1.2+A_2[I]对本实验结果的拟合表明,这六种加盐微团溶液的液-液相分离亦遵从同样的变化规律。从而为揭示各种价型无机盐对两性离子化表面活性物质微团溶液液相分离的作用规律和机制提供了进一步的实验与理论依据。 The effect of six salts with different valence on the phase separation of C8-lecithin micellar solution were investigated by the method of lever rule. It was found that, the variation of the critical temperature (Tc) of the phase separation with the ionic identity and strength also followed the previously suggested formula: Tc=Tc0-A1[I]1/2+A2[I]. Based on the experimental results, the mechanism and the interactions between ions and the molecules of C8-lecithin were also discussed.
