摘要
对PM2 5的化学物种组成及其采样方法进行了概述,侧重介绍了主要的半挥发性成分硝酸铵与有机碳的采样问题。按照无机多元素、水溶性离子和含碳组分概述了PM2 5主要化学物种的分析方法。
In this paper the chemical speciation of PM(2.5) and their corresponding sampling are introduced,with an emphasis on semi-volatile species such as ammonium nitrate and organic carbon.The analysis methods of three major species of PM(2.5) including elements,water-soluble ions,and carbonaceous species are also described.
