| Abstract: | A method of determination of Y, La, Pr, Sin, Ce, Gd and Nd rare-earth elements in Al based alloy by ICP-OES was proposed. The experiment of selection of analysis lines, the effect of matrix and coexist elements on the determination , instrument parameters of the analysis results were carried out. The recovery rate of this method was found in the ranges 98% to 104%, the RSD were less than 4%. The method is simple, rapid and ac- curate. |
