▎ 摘　　要

NOVELTY - Aminated magnetic graphene is prepared by adding 3-6 mmol trivalent iron salt to 40 ml of 0.5-6 mg/ml graphite oxide solution to obtain trivalent iron oxide graphene solution, adding 9-25 mmol of organic base, stirring for 30-120 minutes, placing organic base and trivalent iron oxide and graphite mixed solution in hydrothermal reaction vessel to react at 150-200 degrees C for 8-24 hours, cooling to room temperature, washing with water, centrifuging and drying at 60 degrees C for 24 hours. USE - Method for preparing aminated magnetic graphene (claimed). ADVANTAGE - The method is simple, safe and environment-friendly. DETAILED DESCRIPTION - Amine-based magnetic graphene is prepared by adding 3-6 mmol trivalent iron salt to 40 ml of 0.5-6 mg/mL graphite oxide solution to obtain trivalent iron oxide graphene solution, adding 9-25 mmol organic base to trivalent iron oxide graphene solution to obtain organic base and trivalent iron oxide and graphite mixed solution, stirring for 30-120 minutes, placing organic base and mixed solution of trivalent iron oxide and graphite in hydrothermal reaction vessel to allow reaction at 150-200 degrees C for 8-24 hours, cooling to room temperature, washing with water, centrifuging and drying at 60 degrees C for 24 hours. Ferric salt is ferric chloride, ferric sulfate, ferric nitrate, ferric citrate or iron perchlorate. Organic base is 2-(dimethylamino)ethyl methacrylate, 2-(diethylamino)ethyl methacrylate, 2-(dimethylamino)ethyl acrylate, N,N-dimethylaminoethyl methacrylate, N-(3-dimethylaminopropyl)methacrylamide, triethylamine or ethylenediamine.
