摘要
用两种不同的方法合成了金属离子萃取剂Ｎ，Ｎ—二苄基甘氨酸和Ｎ—正丁基甘氨酸，并以它们的乙醇溶液为固定相，以不同浓度的盐酸为展开剂，用反相纸层析法研究了它们对Ｐｂ２＋、Ｃｕ２＋等５种金属离子的萃取性能。结果表明：两种萃取剂的萃取能力随展开剂的酸度不同而变化。Ｎ，Ｎ—二苯基甘氨酸对５种金属离子的萃取能力强于Ｎ—正丁基甘氨酸。
N,N-diphenyl glycine and N-n-butyl glycine were synthesized by two different methods, they are a kind of extraction agent of metalions. Two extraction agents dissolved in alcohol were used as stationary phases, hydrochloric acid solutions of different concentrations were used as the developers. The extraction powers were studied for Pb2+Cu2+ and so on by reverse paper chromatography. As shown by study the extracting powers of two extraction agents are changed with acidy of developer extracting power N,N-diphenyl glycine is stronger than N-n-butyl glycine for 5 metal ions. The extracting powers of two extraction agents are all the strongest for Pb2+.
