Nanotechnology in environmental sustainability and performance of nanomaterials in recalcitrant removal from contaminated Water: A review

Abstract

In this review article, the implementation of nanomaterials such as metal oxides and their composites, carbon nanotubes, dendrimers, and polymer nanocomposites in wastewater decontamination have been discussed. Nanomaterials have a lot of potentials, due to their high pollution sensing ability and larger surface area. Nanomaterials are ideal for eliminating harmful heavy metals and eradicating severe infections spreading microorganisms, organic waste and inorganic contaminants from the environment. The article reviews recent developments in wastewater treatment using various nanomaterials. Nanotechnology has resulted in multiple effective nano techniques for environmental remediation such as photocatalysis, nano adsorption and nanofiltration, which are more exact and accurate in eradicating recalcitrant. Novel semiconductor photocatalysts, nano adsorbents, nanocomposites, and other nanostructures have been used to overcome these difficulties and achieve maximal performance at a low cost. This review provides the techno-functional applications of nanomaterials in wastewater remediation.
