氢化物——光谱技术快速测定水中汞

Approach for determining of Hg in water by hydride and spectrometry technique

利用流动注射氢化物发生仪器,采用原子吸收光谱法分析技术,创建了快速、准确测定水中汞的方法。此法自动化程度高,分析速度为120次/小时,检出限为0.100μg/L,回收率在95～102%之间,达到了操作简便、检测快速、结果准确的目的。

A high autonatical method for the determination of trace Hg in water with flow injection hydride generation atomic absorption spectrometry （ F1HGAAS ） was studied.Which provided a way to determine trace Hg in water easier, faster and more accurate.On an analysis speed of 120 samples an hour, the determination limitation for Hg was 0. 100μg/L and the reclamation rates were between 95% and 102% The outcome was satisthctory.
