Heterogeneous Photocatalytic Degradation of Disulfoton in Aqueous TiO2 Suspensions: Parameter and Reaction Pathway Investigations

“…The end products are carbon dioxide, water and inorganic mineral salts. [17][18][19] Homogeneous photochemistry, in general, requires high energy photons and rarely enhances the total degradation of the pollutant. Photocatalytic oxidation using semiconductor materials, such as TiO 2 , has been demonstrated as the effective means for organic degradation in a very short time and with high efficiency.…”

Interpretation and Modelling of Environmental Behaviour of Diverse Pesticides by Revealing Photodecomposition Mechanisms

“…Cyanuric acid was found to be the common final photoproduct of all herbicides. Triazine-derivatives are considered to be the representatives of pesticides of the most wide-spread practical application; therefore it is of crucial importance to evaluate their fate in the environment (Vidal et al 1999). It was shown that some triazine herbicides undergo photodegradation to form deaminated derivatives (Mansour et al 1993).…”
