Abstract The present paper shows that the trace amount of gold, platinum and palladium in hydrochloric acid solution can be concentrated by hyperbranched polymer. The new reagent has a rapid adsorption rate and big concentrating capacity. The determination of trace Au, Pt and Pd in sample using carbon powder and strontium carbonate as buffer was carried out by atomic emission spectrometry(AES). Zirconium was selected as internal standard line. The sample was directly loaded into ordinary electrode. The method is simple, rapid and accurate. The condition of determination, and factors of influence were studied. The analysis line of Au, Pt and Pd is 312.3, 306.5 and 311.4 nm respectively. The internal standard line of Zr is 310.7 nm. The linear range of the determination of Au, Pt and Pd is 0-0.20%, 0-0.40% and 0-0.20% respectively. The detection limit of Au, Pt and Pd is 0.010%, 0.003 0% and 0.003 0% respectively. The method has been applied to the determination of Au, Pt and Pd with satisfactory results.
