“…Manufacturing nano‐adsorbents can help provide clean, safe, and affordable water for human consumption. In previous reports, researchers have discussed some of the recent advances that have been made in the use of numerous nano‐adsorbents (including magnetic nanomaterials, carbon nanotubes, titanium, ceria, yttrium, zirconium, copper, perlite, biochar, alumina, and polymeric nanocomposites) for removing As effectively (Ghosh et al., 2021). The removal of heavy metals from water can be executed by physical methods (membrane separation, sedimentation, screening, filtration), chemical methods (chemical precipitation, coagulation, adsorption, ion exchange, solvent extraction and neutralization), and biological methods (using aerobic and anaerobic microorganisms) as discussed by researchers earlier (Abdel‐Raouf & Abdul‐Raheim, 2017).…”
