Gen, R. Zhang, D. D. Huang, Y. Li, C. K. Chan) “Heterogeneous SO2 Oxidation in Sulfate Formation by Photolysis of Particulate Nitrate” (微粒子状の硝酸塩の光分解による硫酸塩形成における不均一系SO2酸化)


Sulfate plays a critical role in atmospheric particulates, and it has been found to be an important component of particulate matter (PM) during severe haze events. Masao Gen et al. (2019) investigate a new pathway for the formation of sulfate during extreme haze events in China. Their work points to a new pathway for sulfate formation, via the oxidation of sulfur dioxide by the NO2 and hydroxyl radicals produced upon ultraviolet irradiation of nitrate. Raman spectroscopy was used to monitor sulfate formation in real time while reactions occurred in a flow cell. Modeling estimates revealed that this reaction is equally or more important to other known sulfate formation pathways mediated by other oxidants (ozone, hydrogen peroxide, and transition metal ions) at pH 4.5–6.
