摘　　要：以 N,N-二苯基甘氨酸的乙醇—苯溶液和 N,N-苯基甘氨酸的乙醇—三氯甲烷溶液为固定相 ,以不同浓度的盐酸为展开剂 ,较系统的研究了 2种固定相对谱、钐等 1 1种金属离子的反相纸层析行为。实验表明 ,N,N-二苯基甘氨酸的乙醇—三氯甲烷溶液对稀土离子的萃取性能优于 N,N-二苯基甘氮酸的乙醇—苯溶液 。N,N-diphenyl glycine diolvedin alcohol-benzeneandalcohol-chloroform were usde as stationary phases, respectively, hydrochlor icacid solutions of differeent concentrations were used as the developers. The revers paper chromatography behaviour were studied ystematicly for 11 rare earthion. As shown by study the extracting power of N,N-diphenyl glycine in alcohol-chlorform for rare earth ions is better than in alcohol-benzene, and two or more mixtures were separated succefully.
