Abstract:
Frequent events of winter haze in China have caused various health issues in large populations. It is believed that the sulfate aerosol produced by a series of physical and chemical reactions of SO2 is an important culprit of haze generation,and the heterogeneous reactions of SO2 on mineral particles is particularly important. Therefore,clarifying the formation mechanism of sulfate on mineral particles is a key scientific problem to analyze the formation of haze. In this paper,the research progresses about the typical heterogeneous reactions of SO2 on various mineral particles were reviewed,the effects of multi-pollutant coexistence system,humidity and light on heterogeneous reactions of SO2 were discussed,the future work related to heterogeneous reactions was also proposed. This paper aims to gain a deep understanding of the mechanism of mineral particles promoting the formation of sulfate and attempts to provide theoretical support for effective haze control.
