ICP-AES法测定硅钙合金中铁、铝、锰

摘要

采用ICP-AES法测定了硅钙合金中的Fe，Al，Mn，并对样品溶解方法、共存元素及基体的影响、内标元素的选择等进行了研究，建立的分析方法简便快速，精密度和准确度较好。%The method for the determination of Fe, Al, Mn in calcium-silicon alloy by ICP-AES has been proposed. The factors such as the preparation of the sample solutions, the interference of matrix and co-exiting elements, the selection of the internal standard element have been investigated. The established method is convenient, rapid and of good precision.
