Photocatalytic degradation of organophosphorus pesticides using floating photocatalyst TiO 2 · SiO 2/beads by sunlight

This paper studies the feasibility of photocatalytic degradation of organophosphorus pesticides using thin films of TiO2. The results show that 0·65 × 10−4mol dn−3 of dichlorvos, monocrotophos, phorate, parathion can be completely photocatalytically degraded into PO within a short time under illumination with a medium pressure mercury lamp of 375 W. The effect of parameters such as he amount of TiO2 attached, initial concentration of organphosphorus pesticides, initial pH, amount of air flow, concentrations of H2O2 and Fe3+ on the photocatalytic degradation are studied. The possible mechanisms of photocatalytic degradation are discussed. It is our assumption that the degradation reactions occur on the surface of TiO2 via primary produced oxidizing species such as the OH radical and O, after 80 h illumination, there is no significant loss of the photocatalytic activity of TiO2.

Investigation of the photocatalytic degradation of organochlorine pesticides on a nano-TiO 2 coated film

The extensive use of organochlorine pesticides (OCPs) has led to significant environmental and health concerns due to their persistence, bioaccumulation, and toxicity. This study investigated the degradation of endrin pesticide using a UV-based iron oxide (Fe3O4) photocatalytic system. Prior, Fe3O4 nanocatalyst was synthesized via co-precipitation and characterized by Fourier transformed infrared spectrophotometer (FTIR), scanning electron microscope with electron diffraction spectroscope (SEM–EDX), ultraviolet spectrophotometer (UV–visible), photoluminescence (PL), and X-ray diffraction (XRD). FTIR showed a Fe–O vibrational peak at 450 cm−1, and SEM revealed irregular spherical-shaped agglomeration, confirming the successful synthesis of iron oxide nanocatalyst. Batch photocatalytic degradation of endrin in aqueous solution using a UV-H2O2-Fe3O4 nanocatalyst-based system achieved 97.87% degradation efficiency, demonstrating its potential as an effective method for removing persistent OCPs from contaminated water. Kinetic studies followed pseudo-first-order kinetics with a R 2 value of 0.9533. Cytotoxicity assessment with HepG2 cells indicated that only one sample (compound 2) exceeded a 10% cytotoxicity value, indicating potential hazardous effects on mammalian cells. The other three samples (compounds 1, 2, And 3) displayed 0% cytotoxicity, demonstrating no toxicity. These findings highlight the effectiveness of photocatalytic degradation in treating pesticide-contaminated water, contributing to the development of efficient and environmentally friendly methods, thereby reducing the detrimental impacts of OCPs on human health and ecosystems.
