Palladium in the waste palladium on carbon catalys was examined by air acetylene flame atomic absorption spectrometry in hydrochloric acid medium through wet processing samples ,removing carbon u-sing H2 SO4 + HNO3 smoking from samples ,reduction by methane acid and dissolving samples by chloro-azotic acid .The results show that the recovery ratio is between 98% and 102% and the relative standard deviation is less than 3% ,which are consistent with the results of fire restoring and the fire assay .
