摘　　要：分别以 N,N’——二羧甲基联苯胺的乙醇——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’——二羧甲基联苯胺对8种贵金属的萃取行为。结果表明 :在乙醇——苯混合溶剂中固定相对贵金属的萃取能力比在氯仿溶剂中强。在高氯酸展开剂中对 Au3+、Ru3+、Rh3+的萃取能力较强 ;在盐酸展开剂中对Pd2 +、Pt4 +、Os4 +、Ir4 +、Ag+的萃取能力较强。N,N'-diethyloic benzidine dissolved in alcohol-benzene and chloroform were used as stationary phases, hydrochloric acid and perchloric acid solutions of different concentrations were used as the developers. The reverse paper chromatography behaviour were studied for 8 noble metals, As shown by study N,N'-diethyloic benzidine dissolved in alcohol-benzene is stronger than in chlorform for extracting power of noble metals. The extracting power is stronger in perchloic acid for Au 3+ 、Ru 3+ 、Rh 3+ and in hydrochloric acid for Pd 2+ 、Pt 4+ 、Os 4+ 、Ir 4+ 、Ag +
