摘要
研究了不同稀释剂中,2-乙基己基膦酸单(2-乙基己基)酯从硝酸介质中对Zn(Ⅱ)的萃取,其萃取能力在不同稀释剂中按正己烷>四氯化碳>苯>氯仿的顺序变化.萃取平衡常数与稀释剂的极性参数DP、S间呈线性关系.
The distribution equilibria of Zn(Ⅱ) between aqueous nitrate solution and HEHEHP in the presence of various diluents have been studied.The extraction equilibrium constants decrease in the following order of diluents: n _hexane,carbon tetrachloride,benzene,chloroform.Diluent effect on the equilibrium constants is discussed.
