纯钛中分析稀土元素,由于它们的化学性质十分相似,所以分离和测定稀土元素一直是分析化学的难题之一。电感耦合高频等离子体(ICP)发射光谱法具有多元素同时测定能力,而且ICP光源有较高的激发能量,灵敏度高,稳定性好等优点。因此本方法应用了去溶的ICP-AES法测定纯钛中稀土元素。结果表明,方法简便,灵敏度高,方法的变异系数在5—
Analysis of rare earth elements in pure titanium, because of their very similar chemical properties, so the separation and determination of rare earth elements has been one of the problems of analytical chemistry. Inductively Coupled High-Frequency Plasma (ICP) emission spectrometry has the ability of simultaneous determination of multiple elements, and the ICP light source has the advantages of high excitation energy, high sensitivity and good stability. Therefore, this method is applied to the determination of rare earth elements in pure titanium by desolvation ICP-AES method. The results show that the method is simple, high sensitivity, the coefficient of variation of the method in the 5-
