摘要:
水溶性类腐殖质(HULIS)气溶胶是大气微细颗粒物(PM2.5)的重要组成部分,它通过影响气溶胶的吸湿特性来影响成云过程,直接或间接影响全球气候变化。选取国际标准的Pahokee泥炭腐殖酸(PPFA)、Suwannee河(美国)提取的腐殖酸(SRHA II)、以及2种Suwannee河(美国)提取的黄腐酸(SRFAⅠ)和黄腐酸(SRFA II)水溶性有机物作为研究对象,采用热光分析法,通过控制反应条件,对HULIS颗粒物中总有机碳浓度的实时变化情况进行研究,从而确定含碳比,分析不同源HULIS气溶胶特性,为大气污染监测研究和试验工作奠定基础,为气溶胶污染的防治提供科学依据。
Abstract:
Humic-like substances(HULIS)aerosol is an important part of fine particles(PM2.5). HULIS may affect aerosol properties, such as their ability to nucleate cloud droplets, or their light absorption, directly or indirectly affect the global climate change. In light of the interest that this class of atmospheric compounds currently attracts, the property of HULIS(Pahokee Peat Fulvic Acid, PPFA; Suwannee River Humic Acid II, SRHA II; Suwannee River Fulvic Acid I, SRFAⅠ; Suwannee River Fulvic Acid II, SRFA II)was comprehensively reviewed. By using the method of thermo-optical analysis, the real-time change of total organic carbon concentration in HULIS particles was studied by controlling the reaction conditions, so as to determine the carbon content and analyze the carbon content for water-soluble humic aerosol. This research will lay the basis for the detection and experiment of atmospheric pollution, and provide a scientific basis for the prevention and treatment of aerosol pollution.
