▎ 摘  要

NOVELTY - The preparation of graphene oxide/modified clay multi-dimensional composite material involves (1) adding modified clay suspension to graphene oxide suspension and mixing uniformly, and (2) subjecting the mixture to ultrasonic dispersion and/or microwave treatment for 1-3 hours to obtain brown mixture, (3) leaving the brown mixture still for 6-24 hours, carrying out suction filtration, washing the precipitate and lyophilizing the filter cake. USE - Preparation of graphene oxide/modified clay multi-dimensional composite material (claimed) used for treating wastewater. ADVANTAGE - The method enables preparation of graphene oxide/modified clay multi-dimensional composite material ensuring strong electrostatic force, reduced agglomeration, uniform dispersibility, increased adsorption performance, easy separation effect and high cycle utilization by simple, easy, energy-saving and environmentally-friendly process.
