【Abstract】 The method for the determination of multi-elements in Ferrum aluminum silicon alloy by ICP-AES has been proposed. Sample dissolution methods are stuelied and the effect of instrument parameter on the determination are examined. The factors such as the preparation of the sample solution, the interference of matrix and coexisting elements have been investigated. Under the optimized conditions, two samples are determined .The RSD(n=6) of this method is between 0.26%～5.1% and the recovery is from 95.5% to 102.7% for all elements tested. The method is convenient , rapid and reproducible and has been applied to multielement analysis of alloy with satisfactory results .更多还原
