本文研究了气相色谱仪与测汞仪联机测定河底沉积物中的有机汞。对不同类型沉积物样品的浸取条件进行了系统研究,可达到完全浸取的效果。分离出的有机汞被氢气还原成汞蒸气用测汞仪检测,可作定量分析。
In this paper, gas chromatography coupled with mercury analyzer was used to determine organic mercury in river sediments. The leaching conditions of different types of sediment samples were systematically studied, and the effect of complete leaching can be achieved. The separated organic mercury is reduced by hydrogen to mercury vapor with a mercury detector for quantitative analysis.
