本文通过实验建立了用火焰原子吸收法测定乙醇胺溶液中的铁含量;本法的测定范围0.1～4.0μg/ml,检测极限0.02μg/ml,相对标准偏差为0.7%,回收率99～104%。 ‘
In this paper, the determination of iron content in ethanolamine solution by flame atomic absorption spectrometry was established. The determination range of this method was 0.1 ~ 4.0μg / ml, the detection limit was 0.02μg / ml, the relative standard deviation was 0.7% and the recovery was 99 ~ 104% . ’
