摘要
本文提出了用高氯酸溶液中的高阶导数光度法直接测定稀土-铝合金中铈、镨、钕、再用差减法求镧的方法。分析结果与X-荧光光谱法结果一致。本方法具有快速、简便和准确的优点。
A direct determination method of cerium,praseodymium and neodymium in the lightrare earth-aluminium alloy by using higher-derivative spectrophotometry in perchloric acidsolution is proposed. The content of lanthanum is determined by substraction. The resultswere in good agreement with those determined by x-ray fluorescence method. The methodis rapid, simple and accurate.
