▎ 摘　　要

NOVELTY - Preparing graphene titanium dioxide nanotube hydrogel involves dissolving graphene oxide in water to obtain aqueous solution of graphene. The titanium dioxide nanotubes is added in aqueous solution of graphene, and mixed to obtain graphene-titania nano-tube solution. The iron (II) sulfate aqueous solution is added in graphene-titania nanotube solution, and mixed to obtain mixed solution. The graphene-titania nanotube hydrogel is prepared by self-assembly by placed mixed solution in mixed water bath. USE - Method for preparing graphene titanium dioxide nano-tube hydrogel used in treating antibiotic waste water (claimed). ADVANTAGE - The method enables to prepare graphene titanium dioxide nano-tube hydrogel is prepared in simple manner, is easy to obtain raw material and used green chemical principle, has no toxic effect, has achieved waste water, and has efficiently removed contain antibiotics.
