Iron oxide-based NM received significant focus on eliminating heavy metals from wastewater. Iron oxides such as α-FeOOH, α-Fe2O3, γ-Fe2O3, Fe3O4, and HFO are most studied. α-FeOOH: α-FeOOH is a competitive adsorbent with high adsorption efficiency, low cost, and environmentally safe. The α-FeOOH nanoscale is reported to remove uranium from water using ferrous and ferric salts. α-Fe2O3: α-Fe2O3 NPs have also been reported to be effective adsorbents for eliminating heavy metals. Α-Fe2O3 NPs effectively report the removal of Cr6+. γ-Fe2O3: γ-Fe2O3, the large surface area of maghemite NPs, contributes to significant adsorption efficiency. With the use of the magnetic field, γ-Fe2O3 nanoparticle easily treats wastewater. It is environmentally friendly and does not produce any secondary pollution. HFO: Hydrous iron oxides are reported to effectively remove heavy metals from wastewater. The affinity to interact with heavy metals and high surface area makes it very effective for removing heavy metals. It removes heavy metals using adsorption, ion exchange, and co-precipitation.
