英文摘要	This paper reports a simple and highly selective method for preconcentrating and separating of trace Pd(II) and Pt(IV) with silica gel bonded by aminopropyl-benzoylazo-4-(2-pyridy-lazo)-resorcinol (ABPR.SG). ABPR.SG is stable in solution from 6 mol/L HCl to pH 7.0 and in common organic solvents. The maximum adsorptive capacity of Pd(II) on ABPR.SG is 362 mu mol/g. After preconcentration and separation by using ABPR.SG column, Pd(II) and Pt(IV) of mu g/L level in artificial water samples can be measured reliably by common spectrophotometry. The maximum concentration factors of Pd(II) and Pt(IV) on ABPR.SG column are 143 and 125 respectively. The chromatographic column packed with ABPR.SG can be reused. The method is simple and efficient.; Chemistry, Multidisciplinary; SCI(E); 2; ARTICLE; 4; 537-541; 18
