PHOTOCATALYTIC 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...

15 صفحه اولNew mechanism of organophosphorus pesticide-induced immunotoxicity.
Organophosphorus pesticides (OPs) are widely used throughout the world as insecticides in agriculture and as eradicating agents for termites around homes. The main toxicity of OPs is neurotoxicity, which is caused by the inhibition of acetylcholinesterase. OPs also affect the immune response, including effects on antibody production, interleukin-2 production, T cell proliferation, decrease of C...
متن کاملPhotodegradation of Octylphenol Using Simulated Sunlight Radiation
This work aims studying the photochemical behaviour of octylphenol (OP) in aqueous solution exposed to simulated UV solar radiation, in lab-scale experiments. The OP photolysis was also investigated by varying different reaction parameters such as: initial pH, initial concentration of OP, reaction temperature, concentration of hydrogen peroxide, presence/absence of dissolved organic matter, HCO...
متن کاملPhotocatalytic Degradation of Humic Acid by Ag/ZnO Nanoparticles under UVC Irradiation from Aqueous Solutions
Introduction: Humic acid (HA) is one the original disinfection byproducts processors in water treatment. So, removing it is necessary before water chlorination. In the present study, photodegredation of humic acid in water using Ag/ZnO nano particle under UVc irradiation in batch system was investigated. Material and Methods: Photocatalytic study was carried out to evaluate the effect of UVc (...
