          摘要:

          我國秋冬季霧霾頻發,對人類健康造成巨大威脅。大氣中SO2經系列物理化學反應產生的硫酸鹽氣溶膠是霧霾產生的元兇,其中礦質顆粒物參與的SO2表面非均相反應尤為重要,因此,厘清礦質顆粒物表面硫酸鹽的形成機制是解析大氣霧霾形成的關鍵科學問題。本文綜述了SO2在不同類型氧化型礦質顆粒物表面非均相反應的研究進展,討論了多污染物共存體系、濕度和光照對SO2非均相反應的影響,并對目前礦質顆粒物表面非均相反應研究中存在的問題進行了評述,旨在加深對礦質顆粒物促進硫酸鹽形成機制的認識,助力揭示我國霧霾的成因,進而為霧霾治理提供理論指導。

          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.
