摘要：
A method for the determination of sulfide based on its interference with the determination of Hg by cold vapor atomic absorption spectrometry is described. The decrease in mercury absorbance at 253.7 nm is proportional to the concentration of sulfide over the range of 10 - 320 ng mL(-1). The limit of detection was found to be 7 ng mL(-1) and the relative standard deviation ( R. S. D.) for the determination of different concentrations of sulfide was in the range of 1.8-2.2%. This method was applied to the determination of sulfide in whole human blood after gas-phase separation.
