电感耦合等离子体发射光谱测定稀土铝合金中稀土和非稀土元素

Simultaneous Determination of Trace Elements in Rare Earth -Aluminum Alloy by Inductively Coupled Plasma-Atomic Emission Spectrometry

本工作用 ICP-AES 法测定稀土-6063变形铝合金中 La、Ce、Pr、Nd、Sm、Gd、Fe、Mg、Ti、Zn,Cu 和 Mn,本方法不用化学分离,可一次同时测定这些元素,并做了 ICP光源参数、基体量变化、酸度(HCl)变化、稀土总量变化、共存元素 Fe 和 Mg 量的变化对被测元素的影响。本方法速度快、准确度高(除 Cu 稍差)。回收率91.0～110.0%,相对标准偏差±1.4～8.0%。

The determination of rare earth and non-rare earth elements in rare earth alu- minum alloy is reported by inductively coupled plasma-atomic emission spectrometry.Ef- fect of acidity,matrix and coexistent elements on the determined elements was studied. This method with good accuracy and reproducibility was compared with the D.C.are and chenical method.
