| Abstract | There are different forms of mercury in the atmosphere, which have different impacts on the environment. At present, the research of mercury determination in atmospheric particulates and its speciation analysis were very limited. In this paper, headspace-solid phase microextraction (HS-SPME) and gas chromatography-inductively coupled plasma mass spectrometry (GC-ICP-MS) were used to detect inorganic mercury and methylmercury in atmospheric particulates. The detection limits of methylmercury and inorganic mercury were 2 ng/L (0.02 ng) and 0.5 ng/L (0.005 ng), respectively, and the lower limits of determination was 8 ng/L (0.08 ng) and 2 ng/L (0.02 ng), respectively, which can be used for the accurate determination of inorganic mercury in atmospheric particulates, as well as for the monitoring of methylmercury in polluted gas or atmospheric particulates in methylmercury polluted area. 收稿日期: 2019-04-09;收到修改稿日期: 2019-05-21 作者简介: 杨坤红 (1975-),男,重庆市人,高级工程师,主要从事生态环境保护监测及科研工作。 共同一作: 谭 清 (1981-),女,重庆市人,高级工程师,硕士,主要从事环境分析与检测。 第 45 卷 第 8 期 中国测试 Vol.45 No.8 2019 年 8 月 CHINA MEASUREMENT & TEST August, 2019 |
