Abstract

The exploration of the cutting edge of wastewater treatment, concentrating on the ever-changing field of heavy metal remediation uses of nanotechnology is a major requisite for sustainability. The investigation covers a wide range of nanotechnology topics, such as photocatalysis, adsorption, catalysis, and novel nanomembranes, providing a thorough grasp of its crucial function in water treatment. Examining specific nanomaterials such as nanoparticles, nanotubes, and nanofibers, the study evaluates their applications, highlighting their unique contributions to heavy metal removal. However, the paper meticulously dissects the challenges hindering the widespread use of nanoparticles in wastewater treatment, with a keen focus on graphene oxide nano-sheets, magnetic nanoparticles, polymeric hydrogels, and activated carbon. Novel techniques incorporating nanotechnology for heavy metal removal are also explored. The conclusion provides a synthesis of findings and offers recommendations for overcoming existing challenges, paving the way for an enhanced integration of nanotechnology in wastewater treatment practices. This paper serves as a vital resource for researchers, practitioners, and policymakers engaged in advancing sustainable and effective solutions for heavy metal remediation in wastewater treatment systems.
