Abstract

2, 4 Dinitrophenol is one of the common pesticides that are used widely in agriculture to combat harmful pests and organisms. As a result of its usual use, there is a great accumulation of its levels in aquatic water. Zinc-doped TiO2 nanoparticles can serve in this field and have achieved excellent results in the detoxification of water using solar light irradiation. Zinc-doped titanium dioxide nanoparticles have been fabricated by the sol-gel method. The new catalyst has been examined in the detoxification of wastewater by removing the dissolved 2, 4 dinitrophenol toxic pesticide. According to the treatment results, Zn-doped TiO2 can remove about 85% of toxic material within 17 minutes. The characterization of synthesized nanoparticles was carried out by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (TEM), and the evaluation of the efficiency of the nanomaterial in the removal of toxic organic residues was carried out by UV-VIS spectrophotometry
