▎ 摘  要

NOVELTY - Preparing composite material involves dispersing graphene oxide powder in N,N'-dimethylformamide, and then subjecting the mixture to perform ultrasonic dispersing in order to obtain a graphene oxide dispersion. Soluble indium salt and 2-aminoterephthalic acid are added to the obtained graphene oxide dispersion, and then uniformly mixing components by the application of ultrasound to obtain a crude indium-based graphene oxide composite. USE - Method for preparing composite material used for adsorbing low concentration rhodamine B dye in water (claimed). ADVANTAGE - The adsorption capacity of composite material for rhodamine B dye is 20.1 times high than zeolite socony mobil-5. DETAILED DESCRIPTION - Preparing composite material involves dispersing graphene oxide powder in N,N'-dimethylformamide, and then subjecting the mixture to perform ultrasonic dispersing in order to obtain a graphene oxide dispersion. Soluble indium salt and 2-aminoterephthalic acid are added to the obtained graphene oxide dispersion, and then uniformly mixing components by the application of ultrasound to obtain a crude indium-based graphene oxide composite. The obtained crude indium-based graphene oxide composite is soaked in N,N'-dimethylformamide and methanol solvent to obtain activated indium-based graphene oxide composite, which is then cleaned to obtain the desired product.
