Determination of Au, Pt and Pd in Biology Samples by ICP-MS

Abstract

The conditions of separation and enrichment for Au, Pt and Pd in geological samples were studied by 717 anion exchange resin. The exchange method was conducted under the optimized adsorption conditions (pH = 3.0). The effects of different enrich methods and different exchange procedures were compared. The present procedures are relatively simple and can be applied with high precision and reproducibility to the analysis of geological samples with wide ranges of concentrations. Finally, the application of our methods was verified by the analysis of geology reference materials.
