利用ICP—AES仪测定稀土铝合金中微量的La、Ce、Pr、Nd、Sm。试样用酸分解,直接上机测定,对光谱干扰情况和仪器参数的选择进行了研究。实验结果和推荐值核对相符。
Determination of trace amounts of La, Ce, Pr, Nd and Sm in rare earth aluminum alloy by ICP-AES. The sample was acidolyzed and measured directly on the machine. The conditions of spectral interference and the choice of instrument parameters were studied. The experimental results and recommended values match.
