摘　　要：本文提出以二乙基二硫代胺基甲酸铋[Bi(DDC)_3作为固定相,硅胶或泡沫塑料为载体,用1%的盐酸溶液淋洗杂质离子,以硫脲的盐酸溶液解脱并以原子吸收测定矿石中痕量钯。A procedure for selective separation of palladium has been developed. It is based on the extraction chromatography of palladium, using bismuth diethy ldithiocarbamate [Bi(DDC)_3] as replacement extractant. 1 % HC1 is chosen as eluent for clean-up the impurities. The separation has been applied to the analysis of traces of palladium in ores, combined with AAS.
