In the area of water purification, nanotechnology offers the possibility of an efficient elimination of contaminants and germs. Currently nanoparticles, nanomembranes and nanopubes used for the detection and removal of chemical and biological substances include metals (eg cadmium, copper, lead, mercury, nickel, zinc), nutrients (eg phosphate, ammonia, nitrate and nitrite), cyanide , Organic, algae (eg, cyanobacterial toxins) viruses, bacteria, parasites and antibiotics. Basically four kinds of nanoscale materials being evaluated as functional materials for water purification, eg. Nanoparticles containing metals, carbonaceous nanomaterials, zeolites and dendrimers. Carbon nanotubes and nanofibers also show some positive results. The nanomaterials reveal a good result than other techniques used in the treatment of water due to its high surface area / volume ratio. It is suggested that these can be used in the future in large scale water purification. It is also observed that the coliform bacteria treated with ultrasonic irradiation for a short period of time before the treatment with Agnanoparticles at low concentration, potentiate the antibacterial effect. In the future, the combination of both may be the best choice for wastewater treatment.
Nanotechnology has revolutionized the plethora of scientific and technological fields; Environmental safety is no exception. One of the most promising and well-developed environmental applications of nanotechnology has been the remediation and treatment of water where different nanomaterials can help to purify water through different mechanisms, including the adsorption of heavy metals and other contaminants, the removal and Inactivation of pathogens and the transformation of toxic materials into less toxic compounds. For this, the nanomaterials have been produced in different forms, integrated in diverse compounds and functionalized with active components. Nanomaterials have also been incorporated into nanostructured catalytic membranes which in turn can help improve water treatment. In this article, we have provided a succinct review of the most common and popular nanomaterials (titania, carbon nanotubes (CNTs), zero-valent iron, dendrimers and silver nanomaterials) that are currently used in environmental remediation and particularly in purification of the water.
