Determination of platinum in alumina-supported automotive catalyst material by electrothermal atomic absorption spectrometry

Platinum (0.01–0.2%) is determined after dissolution in sulfuric and hydrochloric acids and addition of palladium and rhodium to compensate for interelement effects. At the 0.06% level, the relative standard deviation is 2%. The results agree within 4% with those obtained by chemical methods.
