Résumé:

This presentation will focus on the gas  liquid interface processes that potentially represent important sources for the atmospheric chlorine.  Kinetic and mechanistic studies of the reactions of OH and SO4- radicals with Cl- ions will be described.  One of the aims of this research is to evaluate the possibility that the reactions of OH and SO4- radicals with Cl- ions are potential sources of atmospheric chlorine.  This work will focus on the development and application of Diffuse Reflectance Laser Flash Photolysis (DR-LFP) technique to study the reactions listed above at the gas  liquid interface itself.  The goal of this research is aimed to better understand and evaluate the role of interface processes and their impact on the formation and reactions of atmospheric chlorine.
