The collection and determination of atmospheric gaseous bromine and iodine

· Analytica Chimica Acta
A procedure has bcen developed that allows for the isolation, collection, and analysis of atmospheric gaseous iodine and bromine. Particular matter is removed from the airstream to lie sampled by electrosiatic precipitation. The gaseous halogen species are adsorbed onto specially cleaned activated charcoal. After irradiation of the charcoal sample with thermal neutrons, the iodine and bromine are removed from the charcoal, isolated, and purified as the AgX precipitate. The amounts of gaseous iodine and bromine are then determined by BETA -counting. The system works well for air sheds with low particulate iodine and bromine concentrations relative to that in the gaseous phase. In air sheds where the pariiculate halogen predominates, the gas phase measurements are more uncertain. (auth)
