研究了平衡水相酸度、水相盐浓度和温度对三辛胺ＴＯＡ－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ＴＯＡ界面活性随水相ｐＨ及温度升高而降低，随水相盐浓度增加而增加，对有关结果及其与萃取性能的关系做了分析和讨论
The effects of equilibrium aqueous acidity, aqueous salt concentration and temperature on the interface properties of TCA TOA-n-heptane / H2O liquid-liquid system were studied. The interface adsorption parameters cmin and AI were calculated and the TOA activity was found to vary with the aqueous phase pH and temperature increased with the increase of aqueous salt concentration increased, the results and its relationship with the extraction performance were analyzed and discussed
