NOVELTY - An aminated graphene oxide modified heavy metal ion adsorption material comprises activated carbon doped with 1-10 wt.% aminated graphene oxide. USE - Aminated graphene oxide modified heavy metal ion adsorption material (claimed). ADVANTAGE - The aminated graphene oxide modified heavy metal ion adsorption material has excellent adsorption capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of aminated graphene oxide modified heavy metal ion adsorption material, which involves (1) adding 2-5 pts. wt. flake graphite, 300-500 pts. wt. concentrated sulfuric acid and 30-60 pts. wt. phosphoric acid, uniformly mixing, dripping 15-20 pts. wt. potassium permanganate, and stirring at 45-55 degrees C for 9-18 hours, (2) adding 300-500 pts. wt. deionized water into the mixture at 0-5 degrees C, adding 20-50 pts. wt. 10-30 wt.% hydrogen peroxide, and stirring for 5-10 minutes, (3) separating, successively washing the product using deionized water, 10-30 wt.% hydrochloric acid and anhydrous ethanol, and vacuum drying to obtain graphene oxide, (4) dispersing 15-20 pts. wt. graphene oxide in N,N-dimethylformamide solution, adding 40-60 pts. wt. thionyl chloride at 0-5 degrees C, uniformly mixing, increasing the temperature to 65-80 degrees C and continuously stirring for 30-40 hours, (5) dripping 1,6-hexanediamine into the mixed solution, stirring at 0-5 degrees C for 2-6 hours, (6) adding activated carbon to the solution, stirring for 30-180 minutes, and filtering to obtain solid particles, and (7) contacting the solid particles under the protection of inert gas or nitrogen, and heating at 450-600 degrees C, maintaining the temperature for 40-120 minutes.
