Nanotechnology has developed to the point where it is currently possible to manufacture, characterise, andspecifically adjust the functional feat ures of nanoparticles for waste-water treatment. Multiple novel nanomaterials havebeen 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-chemicalproperties. 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 significantenvironmental and financial benefits. However, the nexus between the magnetic and adsorption properties ofsuperparamagnetic nanocomposite materials is what makes them desirable for commercial use. This review articledescribes various synthesis routes for the preparation of nanoparticles having unique properties for their application inwaste-water treatment.
