| Abstract: | A method on speciation analysis of trace mercury in natural water by hydride generation atomic fluorescence spectrometry is introduced in the paper. The experimental conditions and instrumental operation parameters are optimized. The interferences of elements for mercury determination were investigated. The results of standard reference material PACS-1 analysis were well consistent with recommended values. Combined the method established and the standard addition method, the species of trace mercury in campus lake water were analyzed further. The method is proved to be simple, accurate, and suitable for the determination of dissolved mercury species in lake water. |
