[Determination of Se, Fe, Si in electrolytic manganese metal by ICP-AES].
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.
