▎ 摘  要

NOVELTY - Amine functionalized graphene oxide/titanium dioxide material preparation dissolving graphene oxide in 50-100 volume ratio of ethanol and water in a mixed solution under ultrasonic dispersion for 15-25 minutes to prepare graphene oxide solution. 1 pt. wt. titanium dioxide is dispersed in 10-20 pts. wt. aqueous solution under ultrasonic dispersion for 10 minutes to obtain titanium dioxide dispersion solution. 1 pt. wt. prepared graphene oxide solution is added to the prepared titanium dioxide dispersion under ultrasonic stirring for 20-30 minutes. The prepared uniformly dispersed mixture of graphene oxide and titanium dioxide is transferred to a reaction vessel at 100-120 degrees C for 2-4 hours. The obtained product is subjected to centrifuged and washed with ethanol and deionized water. USE - Method for preparing amine functionalized graphene oxide/titanium dioxide material used in adsorbent material selected from solid powder, film, coating, fiber or microsphere for adsorbing methylene blue dye in water body (all claimed). DETAILED DESCRIPTION - The obtained product is dried in an oven at 65-75 degrees C for 15-24 hours. 1 pt. wt. obtained product is dispersed in absolute ethanol to prepare dispersion of 2 mg/ml, and ultrasonically dispersed for 10-20 minutes, and then 2-6 pts. wt. 3-aminopropyltrimethoxy is added with stirring at 80 degrees C for 4 hours. The obtained product is washed with ethanol and water, and then dried at 60 degrees C for 15-20 hours to obtain the product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic infrared spectrum of the prepared amine functionalized graphene oxide/titanium dioxide adsorbent.
