Recent progress in removal of heavy metals from wastewater: A comprehensive review

Novel ZIF-8/CNC Nanohybrid with an Interconnected Structure: Toward a Sustainable Adsorbent for Efficient Removal of Cd(II) Ions

“…A range of techniques have been devised for eliminating heavy metals, such as cadmium, from wastewater, including adsorption, ion exchange, precipitation, coagulation, photocatalytic oxidation, and membrane filtration. 8 Of these techniques, adsorption stands out as a promising method, owing to its high efficiency, low cost, ease of operation, and design flexibility, and it has been extensively researched for heavy metal removal. 9 Thus, selecting or designing an appropriate adsorbent to remove a specific heavy metal is crucial.…”

Effects of magnesium hydroxide morphology on Pb(ii) removal from aqueous solutions

“…When heavy metal ions reach a certain concentration, they can interfere with the functional groups essential for biomolecule activity, displace necessary metal ions within biomolecules, alter the conformation or higher-level structure of biomolecules, and consequently lead to biological dysfunction and various diseases. 3,4 For example, as a highly toxic heavy metal ion, Pb( ii ) can not only cause neurotoxicity in humans and animals, but also impede photosynthesis in plants and suppress the growth. 5,6 Therefore, the treatment of heavy metal-contaminated wastewater has emerged as an urgent environmental concern.…”

Facile fabrication of Fe3O4@Mg(OH)2 magnetic composites and their application in Cu(ii) ion removal

“…2 Hence, it is essential to treat wastewater by removing HMIs. Numerous methods have been employed for this purpose, such as ion exchange, 3 adsorption, 4 chemical precipitation, 5 and membrane separation. 6 Due to its high adsorption effectiveness and simplicity of operation, adsorption is an excellent option for eliminating low-concentration HMIs from aqueous solutions.…”
