Abstract
Photocatalytic degradation of eight azo dyes was conducted in basic medium, studying the influence of various amounts of TiO2 and different light sources, a medium pressure (400 W) and a low pressure (16 W) Hg vapour lamps and lamps for household purposes. The experiments were monitored by UV-vis absorption and the degree of mineralisation was followed by COD variation. Decolouration extents observed are related to dye structure.
