摘要
利用Ｓｅ作基体改进剂，详细研究了汞的石墨炉原子吸收测定条件：并将方法成功地用于人发中痕量汞的测定。
In graphite furnace atomic absorption spectrometry of mercury. addition of 20 g/L selenium improves the peak height for 1 mg/L Hg by 30 times. The effect is due to amalgam formation. The detection limit is 30. 0 ng. The method allows higher ashing temperatures than for solution without Se and can be applied to determination of the trace Hg in human hair,successfully.
