| Abstract: | A method was studied for the determination of trace sodium content in aluminum alloy by ICP - AES. By using hydrochloric acid and hydrogen peroxide 30% to dissolve samples, trace sodium content in the aluminum alloy were determined according to the optimum condition of ICP - AES. the detection limit were 0. 028 μg/mL（588. 995nm）. The results of trace sodium content were between 0. 00014% - 0. 00073%. The relative standard deviations of five samples was less than 0. 25%. |
