Nano Materials in Water Treatment

The most promising and well-developed environmental applications of nanotechnology has been in water remediation and treatment where different nanomaterials can help purify water through different mechanisms including adsorption of heavy metals and other pollutants, removal and inactivation of pathogens and transformation of toxic materials into less toxic compounds. It highlights the uses of nanotechnology to purify water, including separation and reactive media for water filtration, as well as nanomaterial’s and nanoparticles for use in water bioremediation and disinfection. The most extensively studied nanomaterial; zero-valent metal nanoparticles (Ag, Fe, and Zn), metal oxide nanoparticles (TiO2, ZnO, and iron oxides), carbon nanotubes (CNTs), and nanocomposites.
