Abstract
The Role of Soluble Constituents of Atmospheric Aerosols in the Aqueous-Phase Oxidation Mechanisms of S(IV): The Role of Fe(II) and the Effect of Oxalate A contribution to subproject CMD I. Grgic, M. Poznic and G. Bercic National Institute of Chemistry, Hajdrihova 19, P.O.B. 3430, SI-1001 Ljubljana, Slovenia Introduction Our research focuses on processes that can occur in atmospheric water droplets (clouds, fog), where soluble constituents of atmospheric particles may be important in aqueous SO: oxidation under non-photochemical conditions. Atmospheric aerosols are the source of transition metals in cloud and fog water droplets. A fraction of metals present in the particles can dissolve into solution (Zhu et al., 1992). Thus, dissolved metal ions can function as catalysts in atmospheric redox processes occurring in atmospheric water droplets. We report the results of model laboratory experiments with
