Abstract

The photocatalytic degradation of hazardous dye Tropaeoline 000 has been investigated over anatase TiO₂ photocatalyst irradiated with a UV light. The effect of operational parameters i.e. dyes concentration, catalyst concentration, pH, temperature and electron acceptor hydrogen peroxide (H₂O₂) on the degradation rate of aqueous solution of dye has been examined. Results show that the employment of efficient photocatalyst and the selection of operational parameters may lead to complete decolorization and to substantial decrease of the chemical oxygen demand (COD) of the dye solution. The rate of decolorization was estimated from residual concentration spectrophotometrically. At the used experimental conditions the substrate photo oxidation rate follows first order kinetics.
