- Abstract
In order to effectively remove Co2+ from radioactive wastewater, β-cyclodextrin/graphene oxide (β-CD/GO) was synthesized. The factors affecting the adsorption of Co2+in water were determined by static adsorption experiments, and the synthesis and adsorption mechanism of the materials were discussed by using Density Functional Theory (DFT). The results show that β-CD and GO are mainly bonded by ester group and hydrogen bond, the adsorption of Co2+ by β-CD/GO belongs to single molecular layer chemisorption, and the intramolecular diffusion is the main factor of affecting the adsorption rate. The adsorption capacity of Co2+ can reach 95.83 mg/g under appropriate conditions, but it will be affected by interference ions.
