摘要
研究了以电感耦合等离子体发射光谱仪测定硅铝钡合金中铝和钡的方法。考查了方法的线性范围 ,检测限和RSD等指标 ,实验表明 ,方法简便 。
A method for the determination of aluminium and barium in silicon-aluminium-barium alloy with the internal standard by ICP-AES was studied. The method of metlting sample, the interference of dissolved acid and coexisting elements and the working parameters were experimented. The sample was melted by appopriate acid, was changed into solution, the calculating lines were made by standard solution of aluminium and barium, then the concentrations of aluminium and barium were determined by ICP-AES. The linear rang, detection limits and RSD of the method were examined. The method was simple and the results were accurate.
