在综述文献和谱线表数据的基础上，实验研究了ＩＣＰ－ＡＥＳ法测定钢铁中硅的分析线。基体匹配得标样经校正后，Ｓｉ２１２．４１２ ｎｍ和Ｓｉ２５１．６１２ ｎｍ分析线测定钢铁中硅的检出限达０．０００６％，比现行国家标准方法改善约两个数量级。
Based on the literature review and the spectrogram data, the analytical line for the determination of silicon in steel by ICP-AES was studied experimentally. After calibration, the detection limit of Si in Si212.412 nm and Si251.612 nm was 0.0006%, which is about two orders of magnitude better than the current national standard method.
