Abstract

This work wes performed to investigate the photocatalytic decolorization of waste water from textile industries. Methyl orange was used as a target dye with suspended Hombikat TiO$_2$ photocatalyst with a recirculating annular photoreactor. 1 wt % Pt-doped Hombikat thin film tubular reactor with parabolic reflector also wes usedin this experiment. The pH effect and flow rate effect on photobleaching of 0.012 g/l methyl orange solution, AtpH=3 Colour of methyl orange was completely bleached in 30 min with a 20 W UV lamp.
