• Results are reported from experiments investigating the photo-oxidation of a hazardous and refractory aromatic compound (i.e., p-nitrophenol) in aqueous solution using a strong oxidizing agent (hydrogen peroxide) in the presence of ultraviolet irradiation. The combination of hydrogen peroxide and ultraviolet irradiation helped produce hydroxyl radicals characterized by a very high oxidation potential. This high oxidation potential assists in providing complete mineralization of the targeted organic pollutants. The two UV sources tested in the project were an 8 W low pressure mercury vapour lamp and a 125 W medium pressure mercury vapour lamp. Differences in treatment rate observed for the two different types of UV lamps are detailed.
