Photochemical Degradation of a Phenyl-urea Pesticide Chlorotoluron

Abstract

Chlorotoluron photochemical degradation in homogeneous phase (aqueous solutions) was studied. Photolysis by UV radiation, influence of metal (ferric, ferrous) ions, pH, and solvent composition on the reaction rate was investigated. Photosensitizing effect of humic samples was tested. Kinetic characteristics (rate constants, overall quantum yield), products of reactions and extent of mineralization was evaluated.
