“…The adsorption efficiencies for chromium varied from 40 % to 90 % with increasing thickness of the nanocomposite bed [86]. Captivating the magnetic properties of the nanoparticles, including ferrites and oxides, makes them suitable for the recovery process [87,88]. Most of the spinel nanoferrites are superconducting, and removing these nanoparticles after adsorption equilibrium is possible even with a temporary magnetic field [89].…”

The water treatment process by removing heavy metals from polluted sources is explained in detail. Various detection and removal techniques and their modeling for heavy metal removal are reviewed. Detection of heavy metals is possible by several optical, spectroscopic and electrochemical methods. Due to their high efficiencies and accurate evaluation capabilities, several spectroscopic as well as other techniques like neutron activation analysis and X‐ray fluorescence are discussed and found highly significant. Adsorption, photocatalysis, ion exchange, electrochemical methods, membrane filtration, chemical precipitation, and forward osmosis are the most frequently used techniques for heavy metal removal, being up to 100 % efficient to detect and remove heavy metal ions. The design, operation, and key features of all techniques are explained. The regeneration of used adsorbents, resins, and other materials to remove heavy metals is found as key step in the wastewater treatment process.
