摘要：

The possibility of using electrothermal atomic absorption spectrometry (ETAAS) for the determination of trace amounts of Ag, Cd, Co, Fe, Ir, Ni, Mn, Pb, Rh and Ru in pure Pt and Pd is investigated. The influence of the matrix elements, Pt and Pd, on the atomisation of the analytes is studied, using various types of graphite tubes and L'vov platform. The optimum conditions for atomisation of the trace elements from the matrix are discussed. A possible mechanism for the atomisation of the elements in the presence of Pd and Pt is proposed.
