原子吸收光谱法测定水泥中氧化镁含量结果不确定度的评定

Uncertainty Evaluation of the Determination of Magnesium Oxide Contents in Cement by Atomic Absorption Spectrometry

在GB/T176-2008水泥化学分析方法中,用原子吸收光谱法测定氧化镁含量的方法是用于仲裁分析等较为准确的基准法。本文通过对该分析方法中各种因素进行分析,评定氧化镁测定结果的不确定度,从而保证了测量结果的准确性。

Determination of magnesium oxide in cerment by atomic absorption spectrometry was reference method of arbitration analysis according to GB/T 176- 2008, The article analysed various factors affluenced magnesium oxide uncertainty of measurement,discussed evaluation method of magnesium oxide uncertainty of measurement, and finally the test results became more accurate.
