Adsorption Removal of Organic Pollutants using Graphene-based Nanocomposites: Methodologies and Protocols


Adsorption Removal of Organic Pollutants using Graphene-based Nanocomposites: Methodologies and Protocols

J.G. Yu

The fascinating two-dimensional (2D) carbon-based materials, including both graphene and its oxide, have attracted a great deal of attention as efficient adsorbents for the removal of organic pollutants. In order to improve their removal properties such as efficiency, selectivity and so on, it is important to modify their physio-chemical and chemical properties. Various graphene-based composites developed in recent years have revealed a great potential in the treatment of environmental pollutants. Based on their excellent performance for the removal of organic contaminants, undoubtedly graphene-based nanocomposites will find wider practical applications in environmental pollution control.
