Abstract
Pollution of air, soil and water is a global concern for the human society and their environment. Removal of these pollutants from the environment is a huge challenge. Compared to other techniques adsorption techniques are more effective and simple in the removal of contaminants and depend on their pore and surface properties. New size based physiochemical properties formulate nanoparticles with huge range of applications in biomedical, sensors, electronic devices catalyst, membranes removing environmental pollutants and so on. New carbonaceous nanomaterials graphene and graphene oxide which has large high surface area and functional groups signifying their prospective for the adsorption processes. In this review paper, we highlight few current advances in graphene and graphene oxide nanocomposites for the removal of nitrate from water. Nanocomposites material enhances adsorption capacity as well separation efficiency by modifying graphene or else graphene oxide. To increase the adsorption rate by activation of graphene and graphene oxide using nanocomposites will be a promising way for further research in denitrification of groundwater.
