Abstract
Instrumental conditions for the determination of platinum, palladium and rhodium by atomic-absorption spectroscopy with electrothermal atomisation are described for two different instruments. Platinum determinations were investigated further using a third instrument. The effects of acid concentration on peak heights were found to be instrument dependent. This instrument dependence is discussed in terms of the geometries of the various tubes employed in the furnaces. A comparison is made of voltage control and temperature control facilities for the atomisation of the three metals.Keywords
