本文采用稀硫酸溶解试样 ,ICP AES法同时测定电解金属锰中硒、铁、硅 ,通过对溶样酸、锰基体以及背景的研究 ,确定了分析条件。该方法简便具有良好的精密度和准确性 ,相对标准偏差不大于 2 6 8% ,回收率为 98%～ 10 5 %。

The method was established for the simultaneous determination of Se, Fe and Si in electrolytic manganese metal by inductively coupled plasma atomic emission spectrometry (ICP-AES). The sample was dissolved by light sulphuric acid. The analysis conditions were obtained by studying dissolved acid. Mn matrix and background. The recommended method not only proved to be simple and rapid but showed satisfying precision and accuracy as well. The relative standard deviation is less than 2.68% and the recovery is 98%-105%. The t-test showed that no conspicuous difference with typical methods was found.
