摘　　要：介绍了ICP等离子体光谱仪的原理及测定高纯氧化铁中铝、钙、硫、钾、镁、锰、钠和钛等8种杂质元素的分析方法，考察了样品的溶解方案及工作曲线的选择，确定了仪器最佳工作条件和方法检出限。This article introduces the theory of ICP Plasma Spectrometer and the analyzing method of how to determine the impurity elements, such as Al, Ca, Si, S, K, Mg, Mn, Na, Ti etc. in the highly pure ferric oxide. The way of how to dissolve the sample and how to choose the working curves has been introduced as well as the best working condition for the instruments and MDL worunder. This exoteric is used in the sample mensuration, and the result is satisfying.
