摘要
本文报道用微型氢化物发生器原子吸收法测定铋的干扰研究。发现镍、钴、铜对铋的干扰属于液相干扰,锑铅和硒的干扰主要为气相干扰。在石英管原子化器的进口管进行加热预原子化,能抑制形成氢化物元素对铋的干扰,试验了测定铋的各项分析条件。
The interferences of Ni, Co and Cu on Bi were present in the liquid phase, while Sb, Pb and Se mainly in the gas phase. By heating the intake tube of quartz atomizer the suppression of interferences from hydride forming elements was obtained. Other conditions were also studied for Bi determination.
