摘要
用 ICP- AES法同时测定了铁钕合金中主量元素钕及 Al、Si、Mn、Cr、Mg、Zr、Ca等 7种杂质元素。研究了基体元素铁、主量元素钕对杂质元素的光谱干扰 ,选择了合适的分析线和内标线 ,测定了分析方法的检出限 ,回收率为 87%— 113%。方法准确、快速、简便 。
The high concentration Nd and impurity elements Al,Si,Mn,Cr,Mg,Zr,Ca in Fe\|Nd alloys were determined by ICP\|AES.The interference effects of matrix element Fe and high concentration Nd on impurity elements were studied.The suitable analytical lines and internal standard lines were selected.The detect limits of the method were determined.The recoveries are in the range of 87%_113%.The method is accurate,rapid and convenient.
