Photocatalytic degradation of chlorpyrifos and diazinon, which are extensively used as an organophosphorous pesticide in the agriculture field, has been investigated with UV-radiated TiO2 in aqueous phase. Photodegradation rate was increased with increasing pH of the solution. The removal efficiencies of chlorpyrifos and diazinon were 100% after 200 min in pH 9. Photodegradation followed a pseudo-first-order reaction. The rate constants of chlorpyrifos and diazinon were 0.0160min-1 and 0.0180min-1, respectively. NO3-, PO43-, SO42- and Cl- were found as end products on the photocatalytic degradation of chlorpyrifos and diazinon with TiO2/UV.
