A review of photodegradation processes suitable for the treatment of Volatile OrganicCompounds (VOCs) present in the efluents from air-stripping and soil-vapor extraction is presented. This paper outlines and summarizes the essential factors such as kinetics and mechanism, intermediates of degradation processes, and reactor modeling which lead to the successful application of this useful technology. In addition, the effects of operating parameters such as humidity, temperature, additives and types of VOCs are discussed. The review also identijies the areas where further work is needed.
