氢化物发生原子荧光光谱法测定绿豆中砷的测量不确定度评定

Evaluation of uncertainty for determination of arsenic in mung bean by hydride generation atomic fluorescence spectrometry

选取绿豆做样品,根据《JJF1059.1—2012测量不确定度评定与表示》,建立数学模型,对氢化物发生原子荧光光谱法测定砷含量的测量不确定度进行分析评定,找出影响其测量不确定度的主要及次要因素,改善测量过程,有效减小误差。

The uncertainty evaluation is according to the JJF1059.1 2012 Evaluation and Expression of Uncertainty in Measurement. The result showed that the main influencing factor is atomic fluorescence intensity.
