Abstract

The photodegradation of 2,4-dichlorophenoxyacetic acid using illuminated titania particles was studied in buffered water solutions at pH 9.2. A simplified phenomenological model which enables comparison of activity of suspended and supported photocatalyst on the basis of utilisation of light is proposed. The model shows saturation of photodegradation rate with increase of amount of photocatalyst on support or in suspension. The features of the model were verified by studies of the photocatalytic activity of TiO2 suspended and supported on flat glass plate and on floating particles.
