| Abstract: | The separation and preconcentration of platinum group elements and gold with YPA4 chelating resin are described. The adsorption ratio on this resin is 98%-100% for Au, Pt, Pd, Os, 92% for Ir, 90% for Ru, and 87% for Rh, respectively. The resin is treated by high temperature furnace. It is vaporized by continuous laser and introduced in to ICP. Te detection limits are 0. 06 ng/g for Pt, Pd, Ru, Rh, 0. 2 ng/g for Au, and 0.6ng/g for Os, Ir, respectively. The results obtained are in agreement with the recommended values of Standard reference materials. |
