Determination of Relative Contents of Praseodymium Neodymium Metals and Fifteen RE Elements in Their Oxides

摘要: 用电感耦合等离子发射光谱法测定镨钕金属及其氧化物中15个稀土元素的配分量。本方法镨钕回收率99%~100.4%，相对标准偏差小于1%，其余13个稀土元素回收率90%~110%，相对标准偏差小于5%。

Abstract: The relative contents of praseodymium neodymium metals and fifteen RE elements in their oxides are determinated by ICP-AES method. The recovery rate of praseodymium neodymium is between 99% and 100.4%, the RSD is less than 1%, the recovery rate of the rest thirteen rare earth elements is between 90% and 110%, the RSD is less than 5%.
