Silver nanoparticles for wastewater treatment

Abstract Silver nanoparticles (AgNPs) and their hybrids have gained major attention in the field of wastewater remediation strategies. Hybrids of AgNPs with materials like cellulose, activated carbons, chitosan, alginate, graphene oxides, titanium dioxides, silicon dioxide, etc. have been used extensively in wastewater treatment. Dyes such as rhodamine, Congo red, and methyl orange are common contaminants of water. Heavy metal toxicity is another serious concern for water contamination. Additionally, the presence of harmful bacteria and their toxins pose a significant threat to the aquatic ecosystem and human health. AgNPs have desirable antibacterial properties and enhanced adsorption capacities that make them valuable alternatives in removing contaminants from wastewater bodies. Despite the advantages of AgNPs in water remediation, reckless use of these materials could result in the augmentation of major environmental pollution. Hence, careful exploitation of the unique properties of AgNPs is necessary for the effective use of these nanoparticles in wastewater management.
