Palladium in automotive exhaust catalyst was determined by flame atomic absorption spectrometry(FAAS). The analytical conditions and the coexisting elements interference were studied. The catalyst was dissolved by the mixture of H₂O₂ and HCl. Pdin the solution was directly determined by FAAS method. The linearity of working curve ranges from 0.1 to 15μg·mL^-1; the detection limit is 0.029μg·mL^-1; the relative standard deviation(RSD) range is from 0.8% to 2.5%; and the recovery rate range is from 99.6% to 101.2 %. It is asimple and convenient method for accurate analysis of Pd in the exhaust catalysts.
