采用新型金膜吸附-冷原子吸收光谱法测定空气中的汞，在0μg/L～100μg/L范围内线性良好，相关系数为0．9991。方法检出限为1．6 ng/m3，RSD为0．5％～2．7％，测定两种不同浓度的汞标准样品，相对误差为6．1％和3．2％。与两种现行国标方法（巯基棉富集和高锰酸钾溶液吸附法）比较，该方法所需试剂种类少，操作简便、吸附效率好，加标回收率高。

The new type of gold film adsorption-cold atomic absorption spectrophotometric method was a-dopted to determine mercury in air .Good linearity was obtained within the concentration scope of 0 μg/L~100 μg/L, with the correlation coefficient 0.999 1.The detection limit come to be 1.6 ng/m3 , with the RSDs ranged from 0.5%to 2.7%.Relative errors were 6.1%and 3.2% respectively when two different concentra-tions of mercury standard samples were determined by the current method .Compared this method and the two kinds of the current national standard method ( Enrichment of sulfhydryl cotton and potassium permanganate solu-tion absorption method ) , this method needs less kinds of agents and is easy to handle .Meanwhile , this method show high adsorption efficiency and high spiked recoveries .
