| Abstract: | A method for AAS determination of Palladium in Aluminum oxide matfixs by microwave digestion was reported in this paper. The optimum conditions of sample microwave digestion were discussed. The effect of determination medium was studied, eliminating the effect of aluminum by adding the aluminum into the sample solution to reach alu- minum concentration at 4 mg/mL. The results from this method were in conformity with those from spectrophotometry, with the relative standard deviation of less than 1.5 % after 5 replicate determinations. The method is simple and quick, and has high accuracy. |
