Abstract
In this paper, a flow injection on-line clean-up system was developed for d etermination of trace Pt, Pd and Au in the presence of Na+, K+, Ca2+, Mg2+, Fe3+ and Al3+ by electrothermal atomic absorption spectrometry (ETAAS). A column packed with strongly acidic cation-exchange resin (Type 732) was use d as a clean-up column. As Pt2+, Pd2+ and Au3+ can form strong complex anio ns with Cl- in HCl medium, they can be separated from coexisting cations by passing through the clean-up column. The experimental results obtained for trace amounts of gold in reference materials were in good agreement with t he certified values.
