铁矿中痕量钪的ICP-AES分析方法的研究

Study on The Method of Analysis for Trace Scandium in Iron Ores by ICP-AES

系统研究了ICP-AES法的测量条件与基体元素对钪谱线强度的影响和内标元素的校正作用。确定了内标元素、优化了测量条件,建立了铁矿中痕量钪的直接测定方法,本法以钇或镱为内标用于两种铁矿中痕量钪的测定,结果满意。

The influences of ICP-AES measure conditions and the matrix effect on intensity of spectral line of scandium and the calbrated results of internal standard elements have been investigated systematically. The internal standard elements were defined, the measure conditions were optimized, thereby the method of the analysis was developed for direct determination of trace scandium in iron ores. The method was used to the determination of trace scandium in two kinds of iron ores using yttrium or ytterbium as an internal standard element with satisfactory results.
