ICP-AES法测定金属镝与氧化镝中Mn、Ca、La等15个元素

Determination of 15 Elements in Metal Dysprosium and Dysprosium Oxide with Inductively Coupled Plasma Atomic Emission Spectrometry

采用等离子光谱法测定了镝金属中 Mn、Ca、La等 1 5个元素。利用正交试验 L9( 34 )优化了仪器操作条件。方法回收率在 93.6%～ 1 0 8%之间 ,相对标准偏差小于 6.5%。

A ICP AES method for determination of 15 elements in metal dysprosium and dysprosium oxide was developed.The operating conditions of ICP AES were optimized by orthogonal design. Recovery with this method is 93.6%～108% with RSD less than 6.5%.
