塞曼火焰原子吸收法直接测定精铟中的微量铊

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

文章提出在不分离主体铟的情况下于10％的盐酸介质中，采用塞曼火焰原子吸收光谱仪于276．78nm处直接测定精铟中微量铊的吸光度。方法灵敏度高、重现性好、扣背景能力强、测定结果准确可靠，适用于精铟中铊（0．000X％-0．00X％）的测定。

It is reported that micro amounts of T1 in pure In are determined by Zeeman FAAS. The method proves to be good in accurary and reproducibility and is suitable to be used in the analysis of TI（O.OOOX -O.OOX% ）in prue Indium,
