NOVELTY - Magnetic titanium dioxide is dispersed in solvent, ammonia is added, and mixed. The resulting mixture is reacted and product is recovered, to obtain magnetic mesoporous titanium dioxide. Magnetic mesoporous titanium dioxide is dispersed in ethanol, 3-aminopropyl trimethoxysilane is added, and reacted, to obtain aminopropyl-modified magnetic mesoporous titanium dioxide. The aminopropyl-modified magnetic mesoporous titanium dioxide and graphene oxide are mixed, reacted, washed and dried, to obtain magnetic mesoporous titanium dioxide-graphene oxide adsorbing material. USE - Preparation of magnetic mesoporous titanium dioxide/graphene oxide adsorbing material used for separating heavy metals in wastewater and treating organic wastewater. ADVANTAGE - The method environmentally-friendly provides magnetic mesoporous titanium dioxide/graphene oxide adsorbing material having excellent adsorbing capability, mechanical characteristics, and excellent dispersibility, by a simple process. DETAILED DESCRIPTION - Magnetic titanium dioxide is dispersed in solvent, predetermined amount of aqueous ammonia is added, and mixed. The resulting mixture is transferred to reactor, reacted under predetermined conditions and product is recovered using a magnet, to obtain magnetic mesoporous titanium dioxide. The magnetic mesoporous titanium dioxide is dispersed in ethanol, 3-aminopropyl trimethoxysilane is added, reacted under predetermined conditions, washed with ethanol, and dried to obtain aminopropyl-modified magnetic mesoporous titanium dioxide. The aminopropyl-modified magnetic mesoporous titanium dioxide and graphene oxide are mixed in preset ratio, reacted under preset conditions, separated using external magnetic field, washed and dried, to obtain magnetic mesoporous titanium dioxide-graphene oxide adsorbing material.
