摘要
In this work, we synthesized a novel β -cyclodextrin/poly(2-acrylamide-2-methylpropionic acid)/attapulgite (CAMA) hydrogel for uranium(VI) adsorption. Various instrumental techniques such as FTIR, SEM, EDX, and TGA were utilized for characterization of the CAMA. Simultaneously, different important parameters, in specific pH, time, initial uranyl ion concentration and temperature were investigated to evaluate the optimal conditions of the adsorption process. The experiments proofs that the adsorption follows the pseudo-second-order kinetic model so as the Langmuir model, and revealed the maximum adsorption capacity of 434.78 mg g −1 at 298.15 K. Regeneration studies further sighted out the good reusability of the synthesized CAMA hydrogel.
