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.
建立了电感耦合等离子体原子发射光谱法（ICP-AES）同时测定电解金属锰中硒、铁和硅的方法。样品用稀硫酸溶解。通过研究溶解酸、锰基体和背景来确定分析条件。该推荐方法不仅简便快速，而且具有令人满意的精密度和准确度。相对标准偏差小于2.68%，回收率为98% - 105%。t检验表明，与典型方法相比没有显著差异。
