| 摘 要： | 采用高锰酸钾-硫酸液体吸收和原子荧光光谱法测定了气态总汞,探讨并优化了气态总汞测定的条件。当采样体积为15 L时,方法检出限为0.018μg/m3。0.2μg/L和1.0μg/L标准溶液测量结果的相对标准偏差分别为2.5%和1.8%,实际样品测量结果的相对标准偏差为1.9%(n=11),样品加标回收率为88.5%～104.0%。

| Abstract: | Total gaseous mercury was absorbed with KMnO4 -H2 SO4 and detected by vapor-generation atomic fluorescence spectrometry. The experiment parameters were investigated and optimized for the detection of total gaseous mercury. The detection limit was 0.018 μg/m^3 with sample volume of 15 L. The relative standard deviations of two standard solutions with the concentration of 0.2 μg/L and 1.0μg,/L were 2.5% and 1.8%, respectively. The relative standard deviation of the sample determination results was 1.9% （n = 11 ）, and the recovery was 88.5% - 104.0%. |
