Textile industries use different synthetic dye and generate huge volume of textile effluent containing complex mixtures of many polluting substances. The removal of colour from textile wastewater represents a major environmental concern. In this work, the removal of reactive black 5, a textile dye, from aqueous solution has been studied using photocatalysis in a UV annular reactor using TiO2 as catalyst. Photocatalysis is the acceleration of a photoreaction in the presence of a semiconductor catalyst. In this work, effects of reactor operating time, flowrate, solution pH on percent demineralization of dye has been studied. A 94% dye removal was achieved in near neutral solution (pH=6.4) compared to 75% removal in case of alkaline medium (pH=8.4). The kinetic of the photo-reaction has been found to follow Langmuir-Hinshelwood model.
