摘　　要：研究了从硫酸介质中用二－（－２－乙基己基）－膦酸（Ｄ２ＥＨＰＡ）与Ｃ５－７羟肟酸协同萃取Ｇａ３＋及其机理，经斜率法和饱和容量法确定了其萃取Ｇａ３＋萃合物的组成。The extraction mechanism of Ga3+ from sulfuric acid medium with positive synergistic extractant D2EHPA and C5-7 oximine acid has been reported in this paper. The composition of the extractive obtained was determined by the slope method and the saturation extraction capcity method. The extraction equibrium constant was also calculated. At last the ultrared absorption spectrum of the extractive compound was investigated.\=
