摘　　要：以Ｎ，Ｎ－ 二苄基甘氨酸的乙醇 苯溶液和氯仿溶液为固定相，以不同浓度的盐酸和高氯酸为展开剂，用反相纸层析法研究了Ｎ，Ｎ－ 二苄基甘氨酸对１１ 种稀土离子的萃取行为．结果表明：氯仿溶剂固定相对Ｌａ３ ＋ 、Ｎｄ３ ＋ 、Ｅｕ３ ＋ 的萃取能力比在乙醇 苯混合溶剂中大；在高氯酸展开剂中较盐酸展开剂中的萃取能力有所减弱．N,N dibenzyl glycine dissolved in alcohol benzene and chloroform used as stationary phases and hydrochloric acid and perchloric acid with different concentrations used as the developping agents, the reversed paper chromatographic behaviour of 11 rare earth ions was studied systermatically. As shown by study the N,N dibenzyl glycine dissolved in chloroform is stronger than in alcohol benzene for extracting power of La 3+ ,Nd 3+ ,Eu 3+ .The perchloric acid developping agent is weaker than hydrochloric acid for the extracting power of certain rare earth ions.
