摘　　要：研究了复合萃取剂醋酸乙二醛三元体系在 2 5℃时的液液相平衡关系 ,通过自动电位滴定仪测定了两平衡相中醋酸的含量 ,用浑浊法测定了体系的分层曲线 ,并绘出了三元相图。从三元相图看 ,复合萃取剂具有良好的萃取性能。The ternary system of liquid liquid phase equilibrium has been studied at 25 ℃ in this paper.The separation cure of the system was determined by the turbidity method,The tie line data were obtained by analyzing the acetic acid concentration of both phases at equilibrium. The experimental results showed that the mixed extractant was a good extractant.
