Removal of basic blue-41 dye from water by stabilized magnetic iron nanoparticles on clinoptilolite zeolite

Abstract

In this work, Zeolite/Fe3O4 nanocomposite used for adsorption of Blue 41 cationic dye from aqueous solutions in a wide range of concentrations. Analyzes of FTIR, XRD, FESEM, VSM and XRF have confirmed the nature and the structure of Zeolite/Fe3O4 nanocomposite adsorbent. The obtained results and analyzes determined that adsorption process efficiency increases by increasing reaction time, pH and amount of adsorbent and versus, increasing dye initial concentration causes significant decrease of adsorption efficiency. The obtained results of adsorption of isotherm and kinetics study illustrated that data follows Freundlich model and pseudo second order kinetics. Under optimum conditions of pH = 9, dye initial concentration of 100 mg/L, adsorbent dose of 3 g/L and reaction time of 60 min, removal efficiency was obtained 71.4 %. Totally results showed that Zeolite/Fe3O4 nanocomposite can be used by scrutiny of operating conditions of the adsorption process as a adsorbent with high effectiveness and availability, eco-friendly and cost-effective in order to removing dye from waste water of different industries.
