Photodecomposition of carbendazim in aqueous solutions

The kinetic of photodecomposition of carbendazim (methyl-2-benzimidazole carbamate) at different pHs (1, 5, 7, 8 and 11) and at two different concentrations of dissolved oxygen has been studied. According to the experimental results, the photodegradation process follows a first-order kinetic and the degradation rate of carbendazim increases with pH and dissolved oxygen concentration.
