▎ 摘　　要

NOVELTY - Preparing ciprofloxacin adsorption purifying agent based on manganese dioxide/graphene oxide nano composite material comprises (i) preparing graphene oxide using conventional modified Hummer's; (ii) dissolving manganese acetate tetrahydrate and glutamic acid in deionized water to form a solution, where the concentration of manganese acetate tetrahydrate is 0.15 mol/l and the concentration of glutamic acid is 0.34 mol/l; (iii) stirring, adding ethylene glycol into the solution, where the volume of ethylene glycol is 30 times the volume of the solution; (iv) adding deionized water dispersion of graphene oxide into the solution and stirring for 30 minutes to obtain mixture; (v) transferring the mixture to a hydrothermal reaction kettle and reacting at 180 degrees C for 6 hours; and (vi) cooling, filtering, collecting solids, washing and freeze drying. USE - The method is useful for preparing ciprofloxacin adsorption purifying agent based on manganese dioxide/graphene oxide nano composite material. ADVANTAGE - The method is simple and convenient operation, has excellent material performance, good practical prospect and the product has excellent adsorbing and removing performance of the ciprofloxacin.
