A sensitive determination method for mercury speciation analysis was developed.  Four mercury species, mercury ion, methylmercury, ethylmercury, and phenylmercury, were complexed with emetine-dithiocarbamate (emetine-CS(2)), and then injected onto a HPLC instrument coupled with a tris(2,2'-bipyridine)ruthenium(III) chemiluminescence detection system.  The emetine-CS(2) complexing agent was effectively used to measure the concentration in addition to serving as a separation and detection reagent.  The calibration curves for these mercury complexes were linear in the range of 0.050 - 10 μg L(-1) (as Hg).  The limit of detection for (emetine-CS(2))(2)Hg, emetine-CS(2)-methylmercury, emetine-CS(2)-ethylmercury, and emetine-CS(2)-phenylmercury were 30, 17, 21, and 22 ng L(-1), respectively.  The sensitivity of this method enables the determination of mercury species in water samples at sub-ppb levels.  Furthermore, the method was applied to biological samples in combination with acid leaching and liquid-liquid extraction using emetine-CS(2) as an extraction reagent.  The determination results were in good agreement with the values of the certified reference materials.
