| 中文摘要 | the dispersive liquid-liquid microextraction (dllme) combined with high performance liquid chromatography-inductively coupled plasma mass spectrometry for the speciation of mercury in water samples was described. firstly methylmercury (mehg(+)) and mercury (hg(2+)) were complexed with sodium diethyldithiocarbamate, and then the complexes were extracted into carbon tetrachloride by using dllme. under the optimized conditions, the enrichment factors of 138 and 350 for mehg(+) and hg(2+) were obtained from only 5.00 ml sample solution. the detection limits of the analytes (as hg) were 0.0076 ng ml(-1) for mehg(+) and 0.0014 ng ml(-1) for hg(2+), respectively. the relative standard deviations for ten replicate measurements of 0.5 ng ml(-1) mehg(+) and hg(2+) were 6.9% and 4.4%, respectively. standard reference material of seawater (gbw(e)080042) was analyzed to verify the accuracy of the method and the results were in good agreement with the certified values. finally, the developed method was successfully applied for the speciation of mercury in three environmental water samples.
