ICP-AES测定RA合金中铝、镉、铜、铁、铅、锰和硅含量

Determination of Al,Cd,Cu,Fe,Pb,Mn,Si in RA Alloy by ICP-AES

电感耦合等离子体-原子发射光谱法直接测定RA合金中Al、Cd、Cu、Fe、Pb、Mn和Si等元素含量。优选了适宜的仪器测定参数和分析谱线。方法简便快速。回收率在97%—103%之间,相对标准偏差(RSD)<5%。

The elements such as Al,Cd,Cu,Fe,Pb,Mn,Si in RA-alloy are determined by ICPAES. The analytical lines and the working parameters were discussed and optimized. This method is simple and rapid. The recovery is between 97%-103% ,the relative standard deviation is less than 5%.
