摘要：
In this paper, a green synthesized citric acid-crosslinked β-cyclodextrin polymer (CA-β-CD) was applied in removing uranium from aqueous solutions. Citric acid acts not only as cross-linker but also as functional groups for providing adsorption sites. The adsorption properties by varying experimental conditions were carried out by batch tests. The maximum adsorption capacity could reach 150mgg−1. Adsorption process was fitted better with the pseudo-second-order and Freundlich model. Thermodynamic studies proved that adsorption process was sp...
