摘要
提出了用空气-乙炔火焰原子吸收光谱法快速测定纯镍中镁、锰、铁含量,介绍了镁、锰、铁最佳测定条件及呈良好线性范围的浓度,在测定中对样品中的干扰因素进行了综合考虑。该方法具有很好的灵敏度和重现性,具有方法步骤简单、操作容易、干扰少等特点。测定样品中镁、锰、铁含量的相对标准偏差均小于1.0%。标准加入回收率均在97.0%～100.0%范围内。适用于纯镍中镁、锰、铁含量控制分析和样品系统分析。
The air-acetylene flame atomic absorption spectrometry is used to go on the Quick determine Magnesium, Manganese and Iron in the Pure nickel, The deviation RSD 〈 1.0% comparing to standard value, The standard adding recovery is in the range of 97.0%-100.0%. The use of the method fully suited to the control of Magnesium, Manganese and Iron. The practice shows that the method is fully suited to measure the content of Magnesium, Manganese and Iron in the Pure nickel.
