▎ 摘　　要

A procedure was developed for in situ preparation of a composite material consisting of graphene oxide and a copper-containing metal-organic framework by the reaction between 1,3,5-benzenetricarboxylic acid, graphene oxide, and copper sulfate. The materials obtained were examined by X-ray diffraction, IR spectroscopy, scanning electron microscopy, and energy-dispersive X-ray microanalysis. The composite was used for removing organic dyes Congo Red and Methylene Blue from their aqueous solutions. The samples containing 20% graphene oxide showed the highest adsorption rate. The structure of the composite does not change in the course of the sorption.
