大气颗粒物化学组分分析技术研究进展

摘要

The research progress of off-line and on-line analysis technology in chemical composi⁃tions analysis of atmospheric particles are discussed. The sampling technology and sample pretreat⁃ment technology of atmospheric particulates are compared. The off-line analysis technology,includ⁃ing atomic absorption spectrometry (AAS) , inductively coupled plasma mass spectrometry (ICP-MS),X-ray fluorescence spectrometer(XRF),ion chromatography(IC),gas chromatogra⁃phy-mass spectrometry(GC-MS),thermal optical carbon analyzer(TOT/TOR)are discussed deep⁃ly. The developing tendency of on-line analysis technology in chemical compositions analysis of at⁃mospheric particulates is forecasted. The on-line analysis technology including water-soluble ions, OC/EC,chemical composition,particle mass concentration,single particle feature monitoring are also expounded. The research provides a scientific basis for chemical compositions analysis of atmo⁃spheric particles and controlling of mist.%从大气颗粒物的化学组分的研究出发，阐述了离线技术和在线技术在颗粒物组分分析中的应用进展，对于采样技术、样品预处理技术进行了比较分析，对于离线分析技术的原子吸收光谱法（AAS）、电感耦合等离子体质谱仪（ICP-MS）、X射线荧光光谱仪（XRF）、离子色谱仪（IC）、气相色谱-质联联用仪（GC-MS）、热光碳分析仪（TOR/TOT）等进行了深入介绍，展望了在线分析技术在大气颗粒物组分分析中的发展趋势，对水溶性离子组分在线分析、OC/EC在线分析、化学组分在线分析、颗粒物质量浓度在线监测、单颗粒理化特性在线监测等进行了阐述。为颗粒物组分分析提供了依据，也为治理雾霾提供理论依据。
