▎ 摘　　要

A novel method for the preparation of beta-cyclodextrin grafted graphene oxide (GO-beta-CD) has been developed. The GO-beta-CD was characterized by Fourier transform infrared spectroscopy, C-13 NMR spectroscopy, Raman spectroscopy and thermogravimetric analysis. The ability of GO-beta-CD to remove fuchsin acid from solution was also studied. The GO-beta-CD had an excellent adsorption capacity for fuchsin acid and could be recycled and reused. The adsorption capacities of GO-beta-CD for other dye pollutants such as methyl orange and methylene blue were also investigated. The absorption capacities for the three dyes are in the order: fuchsin acid>methylene blue>methyl orange.
