Doped Iron Oxide Nanoparticles forWastewater Treatment

Abstract

Nanotechnology has developed to the point where it is currently possible to manufacture, characterise, and specifically adjust the functional feat ures of nanoparticles for waste-water treatment. Multiple novel nanomaterials have been introduced recently to improve the performance and adsorption capacities of eliminating pollutants from wastewater. Nanocomposites made from Iron oxide nanoparticles (IONPs) consist of maghemite (γ-Fe2O3) and/or magnetite (Fe3O4) particles having average size between 1 to 100 nm. They possess exceptional optical, physico-chemical
properties. The potential for quick magnetic recovery, simple chemical modification, recyclability, solar sensitivity, nontoxicity, and robust design of magnetic oxide nanocomposites encourages their usage in wastewater treatment. Magnetic oxide nanocomposites offer significant promise as new and innovative wastewater remediators, with significant environmental and financial benefits. However, the nexus between the magnetic and adsorption properties of superparamagnetic nanocomposite materials is what makes them desirable for commercial use. This review article describes various synthesis routes for the preparation of nanoparticles having unique properties for their application in
waste-water treatment.
