Abstract
Triazine herbicides like atrazine are common because of their effective weed control and affordable price. (70,000–90,000 tons of estimated annual worldwide use). It is crucial to conduct study on atrazine elimination from the environment because of the substance's stable structure, difficulty in the breakdown, prolonged environmental residence duration, and toxicity to both organisms and people. in surface and groundwater, atrazine was detected over the maximum allowable levels (3 μ g L-1 in the US, 0.1 μ g L-1 in Europe, and 3.0 μ g L-1 by the WHO for drinking water) As a result, many processing technologies, including adsorption, photochemical catalysis, biodegradation, and others, have been developed and are frequently used for atrazine degradation and removal. Recently, attention has been focused on carbon-based nanomaterials, particularly carbon nanotubes and Graphene, as cutting-edge materials for environmental applications. In particular, functionalized derivatives of carbon nanotubes and Graphene remove atrazine from contaminated Water. This critical review evaluates the development of different functionalized carbon nanotubes and graphene employed to remove pesticides and atrazine from polluted water, including the production and characterization processes of functionalized graphene, their applications for atrazine adsorption, and the effects of functionalization science on the adsorption efficiency. Further enhancing their adsorption and better modeling adsorption mechanisms are also indicated.
