Abstract
The study of the heterogeneous photocatalytic oxidation of phenoxyacet ic acid in presence of near-UV illuminated TiO2 is carried out. The La ngmuir-Hinshelwood kinetics model fits the experimental data of phenox yacetic disappearance, and reaction rate and equilibrium adsorption co nstants are reported. The effect of temperature, pH, intensity of inci dent light and mass of catalyst on the reaction rate is ascertained. S ome intermediate products are detected and carbon dioxide was found to be the final product of the reaction.
