Speciation Analysis of Mercury in Natural Water

Separation techniques (extraction, adsorption, electrochemical separation and chromatography) and detection techniques (Spectrophotometry, Atomic Spectrometry, Mass Spectrometry and Electrochemical Analysis) for mercury species in natural water are briefly reviewed in this paper from 22 references. New approaches for trace and ultra-trace mercury speciation analysis in the future should focus on pretreatment system or exploiting a portable instrument so as to realize the species analysis in situ. Moreover, it is worthy mentioning that Liquid Chromatography-Hydrate Generation-Atomic Fluorescence Spectrometry (LC-HG-AFS) with low cost and good performance will have a bright prospect for trace and ultra trace mercury species analysis.
