| 摘 要： | 本文采用２－乙基已基膦酸单（２－乙基已基）酯（简称Ｐ５０７）的磺化煤油溶液从硫酸体系中萃取锌、镉。应用斜率法确定其萃合物组成，井测定出表现萃取平衡常数。通过萃合物及Ｐ５０７的红外光谱确证其萃取机理为酸性络合萃取。

| Abstract: | In this paper,the michanism of extraction of Zinc and Cadmium from sulfuric acid sys-tem with Mono(2-cthylhexyl)2-cthylhexyl phosphonate(P507)is discusscd.The michanism ofextraction is determined by IR spectrum. The formula of complex is given,The extraction equilibrium constant is calculated. |
