当今,在微量Hg的各种分析方法中,还原气化冷原子吸收光谱法是比较简便、快速、灵敏和准确的方法。它已成为世界各国分析化学工作者测定微量Hg的主要常规分析手段。试样中,也常遇到一些含碘的样品,如海带等海洋生物样品,生化样品和以~(131)I标记的胆固醇这类药物样品等。I~-的共存,对分析这些样品中的Hg产生严重干扰。关于消除I~-干扰的方法,文献中有过一些介绍。Lindstedt等和杨春瑾等曾提
Nowadays, reductive gasification cold atomic absorption spectrometry is a simple, rapid, sensitive and accurate method among various analytical methods of trace Hg. It has become the main routine analytical method for the determination of trace Hg by analytical chemistry workers all over the world. Samples, often encountered some iodine samples, such as seaweed and other marine samples, biochemical samples and ~ (131) I-labeled cholesterol and other drug samples. The coexistence of I ~ - produced serious interference with the analysis of Hg in these samples. On the elimination of I ~ - interference method, the literature has had some introduction.
