Environmental pollution such as dyes has been excessively released into the environment and has created a major global concern. Congo Red is a benzidine-based anionic diazo dye with two azo groups. It is toxic to many organisms and is a suspected carcinogen and mutagen. The presence of Congo Red (CR) in water even at very low concentration is highly visible and undesirable. Present work is focused on synthesis of magnetite nanoparticles which showed a high adsorption capacity of Congo Red and is useful in removal of CR from wastewater. Magnetite (Fe3O4) nanoparticles have been successfully synthesized by Sol–Gel method by using Ferric nitrate (Fe (NO3)3.9H2O) and Ethylene glycol (C2H6O2) as precursors in different annealing temperatures. The obtained nanoparticles have been characterized by X-Ray diffraction (XRD), Scanning Electron Microscope (SEM), X-ray energy dispersive spectrometer (EDS) and Particle Size Analyzer. XRD measurements indicate that the obtained nanoparticles are single phase and the particle size increased by increasing the temperature.
