One conceivable mechanism of UV-light induced SO<sub>2</sub> Oxidation to H<sub>2</sub>SO<sub>4</sub>

The electron-excited chemistry of sulfur dioxide oxidation induced by UV irradiation of air with trace O<sub>3</sub> and SO<sub>2</sub> is considered. The importance of this mechanism is evaluated based on recent laboratory experiments on SO<sub>2</sub> oxidation...

Description
Summary:The electron-excited chemistry of sulfur dioxide oxidation induced by UV irradiation of air with trace O<sub>3</sub> and SO<sub>2</sub> is considered. The importance of this mechanism is evaluated based on recent laboratory experiments on SO<sub>2</sub> oxidation in a laminar tube with air induced by UV irradiation. Results show that under respective conditions the route of SO<sub>2</sub> oxidation involving electron excited oxygen molecules may present an additional source of gaseous H<sub>2</sub>SO<sub>4</sub> production to known OH-radical mechanism.
