Adsorption of organic contaminants by graphene nanosheets: A review.
Graphene nanosheets (GNS) such as graphenes and graphene oxides (GOs) have been widely investigated as next-generation adsorbents in both water and wastewater treatment processes due to their unique physicochemical properties and their affinity towards different classes of organic contaminants (OCs). In the last five years, more than 40 articles investigating adsorption of different classes of ...
متن کاملGraphene nanosheets and graphite oxide as promising adsorbents for removal of organic contaminants from aqueous solution.
Graphenes are an emerging class of carbon nanomaterials whose adsorption properties toward organic compounds have not been well understood. In the present study, graphene nanosheets were prepared by reoxidation and abrupt heating of graphite oxide, which was prepared by sequential chemical oxidation of commercial nonporous graphite powder. Adsorption properties of three aromatic compounds (naph...
متن کاملHeavy metals removal from wastewater by using different kinds of magnetite nanoadsorbents: effects of different organic and inorganic coatings on the removal of copper and lead ions
Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of t...
متن کاملRemoval of Metallic and Organic Contaminants from Aqueous Streams by Novel Filtration Methods
Graphite nanofibers, are a novel material that has been developed in our laboratory from the metal catalyzed decomposition of certain hydrocarbons (1). These structures possess a cross-sectional area that varies between 5 to 100 nm and have lengths ranging from 5 to 100 mm (2). High-resolution transmission electron microscopy studies have revealed that the nanofibers consist of extremely well-o...
