| Abstract: | A method of elemental determination is put forward in this paper. Namely, Pt, Pd, Au in 10-20 g samples were preconcentrated in milligram microgranular silver alloy by using fire assay. When compounded in solution, trace platinum, palladium, and gold in the solution were determined by ICP-AES. The detection limits of this method were 0.01, 0.005, and 0.01 microg x mL(-1) for Pt, Pd and Au, respectively. Recoveries of standard were more than 97% with precision of 0.1%, 0.12%, and 0.09% of RSD (n=10), respectively. It has proven that this analysis method is quick, simple and accurate. The method has been applied to the determination of contents of Pt, Pd and Au in samples. |
