Description
Summary:Dowex AG50W-X8 cation exchange resin was used for the separation of interference elements Cu, Ga, Hf, Pb, Rb, Sr, Y in airborne particulate matter in the determination of Pt, Pd and Rh by ICP-MS. Optimal experimental conditions for the cation exchange procedure were examined by simulant sample solutions. The concentration of HC1 in sample solution was 0.8 mol/L. The length of cation exchange column was 4 cm. The elution rate of the cation exchange column was 1 mL/min. An international standard material, BCR-723, for the determination of Pt, Pd and Rh was sued to evaluate the reliability of the cation exchange procedure. The analytical results of BCR-723 showed that the determination values of Pt, Pd and Rh were in good agreement with those standard values, and the removes of interference elements Cu, Ga, Pb, Rb, Sr and Y were over 94%. This indicated that the Dowex AG50W-X8 cation exchange procedure was reliable.
