Poly 3-Thenoic acid sensitized, Copper doped anatase/brookite TiO2 nanohybrids for enhanced photocatalytic degradation of an organophosphorus pesticide

Microwave assisted sol–gel approach for Zr doped TiO2 as a benign photocatalyst for bismark brown red dye pollutant

“…Additionally, the samples exhibited an absorption peak at 1631 cm −1 ; this peak was ascribed to the (H–OH) bending vibration of water molecules. 35 Characteristic absorbance peaks at 549 indicate the stretching vibrations of Ti–O–Ti in UTO which where it is moved towards lower wavenumber of 490 cm −1 (range 400–900 cm −1 ). This change is a result of the successful substitutional doping of Zr 4+ into the lattice of TiO 2 in place of Ti 4+ Due to the development of the Zr–O network, the adsorbed –OH stretching band has shifted.…”

Advanced Equilibrium Modeling for the Synergetic Effect of β-Cyclodextrin Integration on the Adsorption Efficiency of Methyl Parathion by β-Cyclodextrin/Exfoliated Kaolinite Nanocomposite

“…Organophosphates are a commonly employed pesticide in agriculture owing to their great effectiveness and low cost. , Parathion (O, O -diethyl- O -4-nitro-phenyl thiophosphate), a highly effective and frequently employed organophosphorus insecticide, has been extensively determined in the world’s major sources of freshwater. , The World Health Organization (WHO) designated parathion as an extremely potentially toxic and carcinogenic chemical compound that exhibits high levels of water solubility, migration and mobility, biodegradability resistance, and penetration into soil. , As a result, its presence as an organic pollutant within groundwater as well as surface water has been extensively documented, causing significant dangerous and poisonous impacts on human beings, mammals, and aquatic organisms, in addition to its hindering effect on the acetylcholinesterase enzyme within our nervous systems. , …”

“…11,12 The World Health Organization (WHO) designated parathion as an extremely potentially toxic and carcinogenic chemical compound that exhibits high levels of water solubility, migration and mobility, biodegradability resistance, and penetration into soil. 13,14 As a result, its presence as an organic pollutant within groundwater as well as surface water has been extensively documented, causing significant dangerous and poisonous impacts on human beings, mammals, and aquatic organisms, in addition to its hindering effect on the acetylcholinesterase enzyme within our nervous systems. 13,15 Previous toxicity and environmental risks, as well as the deep penetration qualities of parathion insecticides into the soil's profile until groundwater, have issued significant warnings for developing appropriate remediation strategies for these types of chemicals.…”
