▎ 摘 要
NOVELTY - Graphene oxide-based nanocomposite material comprises nanometer graphene oxide and 14-18C alkylamine group. The 14-18C alkylamine group is grafted to the surface of the nano-graphene oxide. USE - Graphene oxide-based nanocomposite material as adsorption material for water treatment (claimed). ADVANTAGE - The graphene oxide-based nanocomposite material has a good adsorption effect on heavy metal ion and organic pollutant in wastewater, higher surface energy and specific surface area, and stronger adsorption effect than general material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1)a method for preparing graphene oxide-based nanocomposite material, which involves: reacting the mixture containing nano-graphene oxide and 14-18C alkylamine to obtain a graphene oxide-based nanocomposite material; and (2)an application method of processing water, which involves: adding graphene oxide-based nanocomposite material to the sewage to be treated, and using the graphene oxide-based nanocomposite material to adsorbing the pollutants in the sewage; where the addition of the graphene oxide-based nanocomposite material is 0.5-1 wt.%, the pH of the sewage is 3-10, and the temperature of the adsorption is 0-70degrees Celsius. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope image of the prepared graphene oxide-based nano composite material.
