| Abstract: | Degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) using UV-illuminated TiO2 suspensions ['Degussa P-25 TiO2 Aldrich TiO2 and Indian origin TiO2 ( TiO2, SD)] and TiO2 fixed to polyester fabric (PE-PVA- TiO2) or TiO2 layer formed on Ti sheet by flame oxidation (Ti/ TiO2) has been studied. Mode of adsorption of 2,4-D over TiO2 has been discussed. Significant chemical oxygen demand (COD) has been removed (> 90%) in > 6h irradiation period. The TiO2 (SD) catalyst suspensions could be reused to treat fresh doses of 2,4-D. The rate of degradation of 2,4-D followed first order kinetics. Pyridine is found to inhibit 2,4-D photodegradation strongly. |
