▎ 摘　　要

NOVELTY - Preparing magnetic molecular imprinting nanomaterial involves mixing 0.1-1.0 mg/ml of graphene/iron(II,III) oxide solution, 0.01-0.06 mg/ml ofloxacin and 10-20 millimoles/L of dopamine in tris hydrochloride solution of pH 8.5. The reactant mixture is stirred for 2-10 hours. The product obtained is collected with a magnet and dried to obtain magnetic molecular imprinted nanomaterial. USE - Method for preparing magnetic molecular imprinting nanomaterial which is used for adsorbing fluoroquinolone antibiotics from water body (claimed). ADVANTAGE - The method enables to prepare magnetic molecular imprinting nanomaterial which has high adsorption rate, high adsorption capacity and strong specificity.
