CHARACTERIZATION AND APPLICATION OF NEW EFFICIENT NANOSORBENT Fe2O3 PREPARED BY A MODIFIED LOW-TEMPERATURE UREA METHOD

Abstract

In this work, low-cost non-conventional nanostructured Fe₂O₃ was produced by a modified low-temperature urea method (MLTUM-Fe₂O₃). Non-magnetic amorphous nanoparticle MLTUM-Fe₂O₃ with a bouquet like morphology is found to play as an effective sorbent media to remove textile dye Reactive Blue 19 from textile industries dye effluents over a wide range of pH. The nanoparticles were characterized by X-ray powder diffraction analysis (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), FTIR and TGA. The surface area was measured by Brunauer-Emmett-Teller (BET) analysis. SEM image reveals bouquet like morphology with average particle size about 50 nm. The maximum sorption capacity of the sorbent is found to be 271.00 mg g^–1 for Reactive Blue 19 and the data fitted with different isotherm models. Study on sorption kinetics shows that sorption of Reactive Blue 19 onto iron oxide follows pseudo-second-order kinetic.
