摘要
研究了平衡水相pH值、水相介质及温度对伯胺N1923 正庚烷/H2O液 液体系界面性质的影响,计算了界面吸附特性参数cmin和AⅠ.发现N1923的界面活性随平衡水相酸度、介质浓度或电荷的增加而增加,随温度升高而下降,并对有关结果及其与萃取性能的关系作了分析和讨论.
The influence of equilibrium aqueous pH value, aqueous medium and temperature on the interfacial extraction property of primary amine N1923 is studied. The interfacial parameters cmin and AⅠ of N1923 are calculated. The interfacial activity of N1923 goes up with the increase of equilibrium aqueous pH value, and concentration of aqueous medium or charge, or goes down with the increase of temperature. The relation between the interfacial property and some relevant results are also discussed.
