| Abstract: | The iron content in palladium chloride was determined by the atomic absorption spectrophotometer. The various uncertainty sources influencing the determined results were analyzed and evaluated through a series of experiments. The results show that the uncertainties mainly come from the dilution process of the standard solution, the fitting process of the working curves and the repetitive determining process of the samples. The determined iron content in palladium chloride is （32.1 _＋ 2.0） mg/kg. |
