汞是车间空气中的有毒物质，它对人体的危害很大、目前洲汞主要采用冷原子吸收光谱法和二硫晚比色法［1］，或采用无火焰原子吸收的专用设备氢化物发生器［2］，前者灵敏度较低，后者设备较昂贵，不易推广普及。我们尝试用大型气泡吸收管代替氧化物发生器，用原子吸收测定车间 Mercury is a toxic substance in the air of the workshop, which is harmful to the human body. At present, mercury is mainly produced by cold atomic absorption spectrometry and spectrophotometry of disulfide [1], or hydride of special equipment without flame atomic absorption [2], the former is less sensitive, the latter is more expensive equipment, not easy to promote popularization. We try to replace the oxide generator with a large bubble absorber and use the AAS
