▎ 摘　　要

NOVELTY - Preparing glycine derivative-graphene oxide composite material comprises (i) preparing graphene oxide from flake graphite as a raw material, and freeze-drying graphene oxide; and (ii) dissolving the graphene oxide with anhydrous N,N-dimethyl formamide to obtain the graphene oxide solution, adding N,N-dihydroxyethyl glycine, mixing uniformly, performing esterification reaction under the condition of anhydrous catalyst, and drying. USE - The material is useful in the selective adsorption and separation of rare earth ions and organic pollutants in aqueous solutions (claimed). ADVANTAGE - The material has stable structure, different adsorption capacity, realizes the high-efficiency adsorption of the pollutant in the aqueous solution and separating and enriches the inorganic organic pollutant and reduces the production cost with great economic value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for glycine derivative-graphene oxide composite material prepared by the above mentioned method.
