摘要
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。
The effect of equilibrium aqueous pH values, aqueous NO - 3 and temperature on the interfacial properties of trioctylamine (TOA) have been studied. The interfacial parameters, c min and A I, of TOA have been obtained. The interfacial activity of TOA increase with increasing equilibrium aqueous pH values and concentration of aqueous NO - 3,or decreasing temperature .The relationship between the interfacial properties and the extraction reaction have also been discussed.
