ICP－AES法中Nd_2O_3对其它稀土元素的光谱干扰的初探及其校正

THE SPECTRAL INTERFERENCE OF NEODYMIUM OXIDE FOE OTHER RARE EARTH ELEMENTS AND CORRECTION BY ICP-AES

在ＩＣＰ－ＡＥＳ法中，Ｎｄ对其它稀土元素的光谱干扰严重。且随着其浓度的增加，具有加和性。本文研究了它的干扰情况，并采用校正系数来消除这种干扰。对样品的标准加入，各元素的回收率在８４～ｌ１６％之间，ＲＳＤ小于８．４％。

d emisssion spectrum is complcx. Its spectral interfercnce for other rare earth ele-ments is linear with the concentration increased of neodymium. In this paper,the corrctioncoefficient of Nd_2O_3 for other rare earth elements has been used to overcome the interference.The recovery are 84～116%。 RSD is less than 8.4%.
