摘　　要：依照GB 5009.76-2014,选取代表性样品,从标准溶液溯源,探索测定食品添加剂中砷含量的数学模型,对检测过程中引入的不确定度进行了分类和量化,系统全面地评定了各个不确定度分量,并给出了运用该方法检测的不确定度评定结果。According to GB 5009.76-2014, the mathematical model for determination of arsenic content in food additives was introduced by investigating from the standard solution with a representative sample. The components of uncertainty in the detection process were classified and quantified, and were evaluated systematically. The uncertainty evaluation for determination of arsenic content in food additives by hydride generation-atomic fluorescence spectrometry was established.
