NOVELTY - Application of graphene/azatriene-zinc ferrite intelligent photocatalyst in selective adsorption and photocatalytic denitrification of ammoniacal nitrogen-containing wastewater. USE - Application of graphene/azatriene-zinc ferrite intelligent photocatalyst in selective adsorption and photocatalytic denitrification of ammoniacal nitrogen-containing wastewater (claimed). ADVANTAGE - The method utilizes graphene/azatriene-zinc ferrite intelligent photocatalyst capable of selectively adsorbing and photocatalytically denitrifying the sewage under visible light, ensures that photocatalytic denitrification is repeated for 5-10 times, and ammoniacal nitrogen removal rate is above 95%, and enables the preparation of intelligent photocatalyst by simple process at low cost under easily controlled conditions with high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/azatriene-zinc ferrite intelligent photocatalyst, which involves dissolving soluble zinc salt, soluble iron salt, and graphene or azatriene in a solvent, uniformly mixing, adjusting the mixed solution to be alkaline, and reacting the mixed solution at 150-200 degrees C for 6-10 hours.
