| Abstract: | 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. |
