摘要
阐述了大气污染物的物理及化学特性,及污染物与空气中痕量污染气体的相互作用,探讨了细颗粒物表面多相化学反应的研究方法,评述了多相化学反应的研究的若干进展。有研究表明NO2可以促进SO2转化为硫酸盐,但是其发生非均相反应的机制尚不清楚。建议可以采用更接近大气环境中的烟雾箱,对其反应机制进行进一步研究。
The physical and chemical properties of atmospheric particulates and their interaction with trace gases in the atmosphere were reviewed, and discussing the research methods of the multiphase chemical reaction on the surface of fine particles, reviewing some progresses in the study of heterogeneous chemical reactions. The research showed that N 02 on the surface can promote the conversion of SO 2 to sulfate has been found,but the mechanism of its heterogeneous reaction has not been clarified. It is suggested that the reaction mechanism can be further studied by adopting a smoke box closer to the atmospheric environ-ment.
