| Abstract: | The trace mercury in potassium nitrate reagents was determined by intermittent flow-hydride generation-atomic fluorescence spectrometry. The optimum conditions for the determination of trace mercury were developed. The detection limit obtained for mercury was 0.05 ng/mL and the recovery was in the range of 97.8% - 101.2%. |
