NOVELTY - Use of graphene/graphene-ferrite copper intelligent photocatalyst in selective adsorption and catalytic denitrification. USE - The graphene/graphene-ferrite copper intelligent photocatalyst is useful in selective adsorption and catalytic denitrification (claimed). ADVANTAGE - The method is simple; has cheap raw material; and is easy to control. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for (1) use of graphene/graphene-ferrite copper intelligent photocatalyst comprising adding the living intelligent photocatalyst to the water containing ammonia nitrogen, to form a mixed system and irradiating the mixed system with visible light, so that the water of ammonia nitrogen is degraded into nitrogen gas for the removal of ammonia nitrogen in water; and (2) preparing the graphene/graphene-ferrite copper intelligent photocatalyst comprising dissolving the soluble copper salt, soluble iron salt and graphene/graphene-ferrite in the solvent, mixing uniformly, adjusting the mixed solution to be alkaline and heating the mixed solution at 150-200 degrees C for 6-10 hours.
