对火焰原子吸收光谱法测定人工海水中铁的测量不确定度来源进行了分析,并对各不确定度分量进行了量化,求得合成标准不确定度和扩展不确定度分别为0.027m g/L和0.053m g/L。
The sources of measurement uncertainty for determination of iron in artificial seawater by flame atomic absorption spectrometry were analyzed, and the components of each uncertainty were quantified to obtain the synthetic standard uncertainty and extended uncertainty of 0.027mg / L and 0.053 mg / L.
