Chemical generation of iodine atoms

The chemical generation of atomic iodine using a chemical combustor to generate the atomic fluorine intermediate, from the reaction of F2 + H2, followed by the production of atomic iodine, from the reaction of F + HI, was investigated. The maximum conversion efficiency of HI into atomic iodine was observed to be approximately 75%, which is in good agreement with the theoretical model. The conversion efficiency is limited by the formation of iodine monofluoride at the walls of the combustor where the gas phase temperature is insufficient to dissociate the IF.
