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

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