【摘要】 <正> 铝中稀土总量的测定一般采用分光光度法,方法简单、快速,准确度较高。而纯铝中稀土分量的测定报导较少,曾有采用发射光谱分析。用ICP-AES法测定合金、混合稀土中单一稀土已有不少报导。本文在上述工作的基础上针对纯铝试样进行了试验。选择了最佳激发条件,更多还原

【Abstract】 This paper described the rapid determination of La、Ce、Pr and Nd in aluminum. The matrix effects and spectral interference have been investigated. La 398.8nm, Ce 413.7nm, Pr 414.3nm和Nd 401.2nm are selected as analytical lines. The results show that the accuracy is good. The procedure is simple and suitable for routine process control analysis.更多还原
