Adsorption of Acid Red 97 by Α-Fe2o3 Nanopowder: Isotherm and Kinetic Studies

Abstract: α-Fe2O3 nanopowder was prepared by solution combustion synthesis using ferric nitrate as oxidiser and oxalyldihydrazide (ODH) as fuel. The characterization of the nanopowder was done by powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The potential of the nanopowder in the adsorption of Acid Red 97 dye was carried out at room temperature. The effect of parameters such as the adsorbent dosage, contact time and initial dye concentration was studied. Isotherm and kinetic studies were employed to analyze the adsorption data. The nanopowder was effective in removal of 20 ppm dye solution. The adsorption efficiency decreased as the initial concentration of the dye solution increased. The adsorption followed pseudo-first order kinetics and obeyed Dubinin-Radushkevich and Temkin adsorption isotherms.
