N263-α-HiBA推拉萃取色谱分离痕量Tm、Yb、Lu

摘要: 研究了Ｎ２６３－α－ＨｉＢＡ推拉萃取色谱法分离痕量Ｔｍ、Ｙｂ、Ｌｕ，得到了各稀土离子的分配比与α－ＨｉＢＡ酸根浓度的关系式，并采用流动相酸度梯度淋洗和α－ＨｉＢＡ浓度梯度淋洗两种途径实现了痕量Ｔｍ、Ｙｂ、Ｌｕ的完全分离。

Abstract: SEPARATION OF TRACE Tm,Yb,Lu BY MEANS OF“PUSH-PULL”EXTRACTION-CHROMATOGRAPHY WITH N263-α-HiBA SYSTEMWang Wushang;Yang Yusheng;Li Yinming(Northwest Institute of Nuclear Technology,P. O. Box 69（17）,Xi’an 710024)Abstract:The separation of trace Tm,Yb ,Lu by means of“push-pull”extraction-chromatography with N263-α-HiBA system is studied．The relation between distribution ratio of each rare earth ion and α-HiBA acid ion concentration is obtained．Complete separation of trace Tm,Yb,Lu from each other is accomplished with acidity gradient elution or α－HiBA concentration gradient elution.Keywords: “Push-pull”extraction-chromatography Tm Yb Lu
