SYNTHESIS AND CHARACTERIZATIONS OF MULTIFUNCTIONAL IRON OXIDES PREPARED VIA MODIFIED CO-PRECIPITATION METHOD

Abstract

Iron oxide nanoparticles have garnered significant attention due to their unique physicochemical and magnetic properties making them suitable for diverse application in environmental remediation ,biomedical  diagnostic and catalysis .this study focuses on the synthesis of iron oxide via the co precipitation method followed by surface modification using silica gel to enhance their stability and adsorption efficiency .further the silica  modified iron oxide nanoparticles were doped with silver nitrate to form composite materials with  improved functional properties. The synthesized materials were characterized using FTIR and the point of zero charge to investigate surface functionalities and charge behavior. Their effectiveness was assessed for the adsorption and degradation of methylene blue dye from aqueous media under various experimental condition including adsorbent dose,dye concentration , and contact time. The result demonstrated that both modified and silver dropped iron oxide naoparticles exhibited  excellent dye removal efficiencies with AGMO achieving up 99% degradation within a short reaction time.this study  highlight the potential of modified iron based nanomaterials as cost-effective and environmentally friendly adsorbent for wastewater .
