NOVELTY - The preparation method of magnetic catalytic adsorption material involves (i) adding graphene oxide powder to deionized water, ultrasonically processing, adding potassium hydroxide and ethylenediamine-( beta )-cyclodextrin, stirring, reacting to obtain homogeneous black solution, centrifugally separating, washing, and vacuum drying to obtain supramolecular ethylenediamine-( beta )-cyclodextrin-graphene oxide, (ii) using ethylene glycol as solvent, uniformly mixing supramolecular ethylenediamine-( beta )-cyclodextrin-graphene oxide with titania and iron(III) chloride hexahydrate, and stirring. USE - Preparation of magnetic catalytic adsorption material (claimed). ADVANTAGE - The environmentally-friendly method enables the preparation of magnetic catalytic adsorption material efficiently with high yield. DETAILED DESCRIPTION - The preparation method of magnetic catalytic adsorption material involves (i) adding graphene oxide powder to deionized water, ultrasonically processing for 0.5-4 hours, adding potassium hydroxide and ethylenediamine-( beta )-cyclodextrin, stirring at room temperature for 10-50 minutes, reacting at 70-90 degrees C for 20-30 hours to obtain homogeneous black solution, centrifugally separating the solid-liquid products, washing the solid-liquid product until the pH is 7, and vacuum drying to obtain supramolecular ethylenediamine-( beta )-cyclodextrin-graphene oxide, (ii) using ethylene glycol as solvent, uniformly mixing supramolecular ethylenediamine-( beta )-cyclodextrin-graphene oxide with titania and iron(III) chloride hexahydrate, stirring for 1-3 hours, adding sodium acetate and polyethylene glycol, mixing for 0.5-2 hours, charging the mixture into a high pressure autoclave, heating at 170-200 degrees C, reacting for 12-24 hours, magnetically separating solid-liquid product, and drying.
