  • 摘要: 为研究青藏高原大气颗粒物化学组成特征,利用Andersen分级撞击式采样器进行大气颗粒物分级采样,建立并优化HNO3+H2O2+HF混合酸密闭消解的体系,并结合电感耦合等离子体质谱分析其中21种元素.结果表明,Na、Mg、Al、K、Ca、Fe元素浓度分别为469.12、286.61、430.75、390.92、783.59 ng·m-3和1289.32 ng·m-3,占所测元素的97.8%.粒径分布显示,Na、Mg、Al、K、Ca、V、Cr、Mn、Fe、Ni、Sr、Ba在5.8-9.0 μm粒径范围出现峰值;Co、Cu、Zn、As、Se、Mo、Cd、Tl、Pb在0.43-0.65 μm和5.8-9.0 μm粒径范围出现双峰.
    Abstract: In order to investigate the chemical characteristics of particulate matters(PM) on Tibetan Plateau, samples were collected by Thermo Scientific Andersen impactor. A method was developed for the determination of trace elements in the PM by ICP-MS with closed vessel digestion using a combination of HNO3 +H2O2+HF. The results showed that the concentrations of Na, Mg, Al, K, Ca and Fe were 469.12, 286.61, 430.75, 390.92, 783.59 and 1289.32 ng·m-3, which accounted for 97.8% of all the elements. Furthermore, Na, Mg, Al, K, Ca, V, Cr, Mn, Fe, Ni, Sr and Ba were mainly associated with coarse particles with a peak at 5.8-9.0 μm. And Co, Cu, Zn, As, Se, Mo, Cd, Tl and Pb had a multi-mode distribution, with peaks at 0.43-0.65 μm and 5.8-9.0 μm.
