| Abstract: | The interference of the determining palladium in catalysts supported on aluminum oxide by ICP\|AES was reported.The interference conditions of inorganic acid and carrier were discussed.Pd in Pd/Al\-2O\-3 was determined by matrix matching method in order to deduce the interference of H\-2SO\-4 and Al\-2O\-3 matrix.The recoveries are higher than 96%,and the relative standard deviation are lower than 3%( n =9). |
