Ozone chemiluminescence in environmental analysis

The chemiluminescence arising from the reaction of ozone with a plethora of compounds is a powerful analytical tool. The applications related to environmental analysis are reviewed in this paper. The various methods of ozone generation and calibration of ozonizers are also discussed. The design and construction of a gas phase ozone chemiluminometer is presented. The apparatus was used to evaluate the ability of halogenated compounds to deplete ozone. The results indicate that gas phase ozone chemiluminescence can be successfully used for monitoring major environmental problems.
