Abstract

Textile effluents characteristically contain colored compounds resulting from dyes unfixed to fibers during the dyeing process that cause serious environmental problems. An alternative process to prevent environmental contamination by these dyes is to oxidize them through photocatalysis in the presence of semiconducting oxides such as TiO₂. In this sense, commercial TiO₂ has been used as a catalyst in the photocatalytic study of discoloration of textile dye C.I. reactive orange-122 aqueous solutions. The photocatalytic reactions were carried in a thermostatized glass reactor and irradiated with a 15-W lamp. It was attained 100% dye discoloration in 120 min of reaction. This result indicates the efficiency of the TiO₂ photocatalysis method in the discoloration of the studied dye
