Photocatalytic degradation of mecoprop and clopyralid in aqueous suspensions of nanostructured N-doped TiO2.
The work describes a study of the oxidation power of N-doped and undoped anatase TiO(2), as well as TiO(2) Degussa P25 suspensions for photocatalytic degradation of the herbicides RS-2-(4-chloro-o-tolyloxy)propionic acid (mecoprop) and 3,6-dichloro-pyridine-2-carboxylic acid (clopyralid) using visible and UV light. Undoped nanostructured TiO(2) powder in the form of anatase was prepared by a so...

متن کاملPhotocatalytic degradation of 4-nitrophenol in aqueous TiO2 suspensions: Theoretical prediction of the intermediates
The kinetics of the photocatalytic degradation of 4-nitrophenol (4-NP) in the presence of TiO2 has been investigated experimentally and theoretically. The effects of the catalyst loading, the initial concentration of 4-NP, H2O2 and the added Cu2+ ions on the degradation rate have been examined. A pseudo-first order kinetic model has been used to describe the results. A linear dependence of the ...
متن کاملPHOTOCATALYTIC DEGRADATION OF THE ORGANOPHOSPHORUS PESTICIDE FENTHION IN AQUEOUS SUSPENSIONS OF TiO2 UNDER UV IRRADIATION
In present study the photocatalytic degradation of the organophosphorus pesticide fenthion, under UV irradiation in the presence of titanium dioxide (TiO2) photocatalyst, in aqueous suspensions has been investigated and compared with the photodegradation by hydrogen peroxide (H2O2) solution as an oxidant agent. The experiments were carried out in a 250mL pyrex UV laboratory-constructed photorea...
متن کاملStudying the Photocatalytic Degradation of Tri-n-Butyl Phosphate Using Nano Nd-Doped TiO2
Photocatalytic method was used as an efficient and simple way for degradation of tri-n-butyl phosphate (TBP). In contrast to other methods, in this method the mineralization occurs and no twin pollution is generated. Nd doped TiO2 was synthesized via sol gel process and characterized by XRD and TEM tecniuqes. Then it was used as photocatalyst for TBP degradetion. It was found that the solution ...
