塞曼火焰原子吸收法直接测定精铟中的微量铋

Direct Determination of Trace Amounts of Bismuth in Pure Indium by Zeeman Flame Atom Absorption Spectrometry

文章提出了在不分离主体铟的情况下于5％的硝酸介质中，采用塞曼火焰原子吸收光谱仪于223.1nm处直接测定精铟中微量铋的吸光度。方法灵敏度高、重现性好、扣背景能力强、测定结果准确可靠，适用于精铟中铋（0．0001％-0.008％）的测定。

It is reported that micro amounts of Bi in pure In are determined by Zeeman FAAS. The method proves to be good in accurary and reproducibility. It is suitable to be used in the analysis of Bi（O. 000 1% - 0. 000 8% ）in pure indium.
