Abstract
Abstract Dicofol is an organo chlorine pesticide used for variety of fruit, vegetable and field crops. It is moderately toxic to humans and may absorbed through ingestion, inhalation or skin contact. Symptoms of continuous exposure to dicofol may have included dizziness, weakness and vomiting, nausea from ingestion. This is highly toxic to aquatic organisms like fish, aquatic invertebrates and algae. The present work signifies the preparation of nanoparticles of pure ZnO using precipitation method with sulfates of metallic precursors. Further the crystalline and structural analysis was being observed by XRD (X Ray Diffraction) and SEM (Scanning Electron Microscope). SEM obtained pure ZnO nanoparticle size is 200 nm and also gives information about surface topography and composition of the sample. XRD is used for phase identification of a crystalline material and FTIR (Fourier Transmission of Infra Red) spectroscopy observes chemical properties. ZnO exhibits catalyst activity for degradation of Dicofol was investigated. And the maximum removal percentage was obtained by varying different conditions of parameters such as time, dosage, pH and temperature. From the experiments, the percentage removal of Dicofol using ZnO was found to be 88.4%.
