Abstract
The photooxidation of phenol in aqueous solution in the presence of po lycrystalline TiO2 powder was used as ''test'' reaction in order to in vestigate the influence of incident light intensity and of some physic al and chemical parameters on the actual absorbed photon flows and on the reactivity. The physical parameters investigated were the surface area and the size of particles while the chemical parameters investiga ted were the initial pH of the dispersion and the presence in the reac ting medium of additives affecting the photoreactivity such as Cl- and H2O2.
