A novel poly(β-cyclodextrin)/bentonite composite (β-CD/BNC) was successfully prepared through graft polymerisation by using ammonium persulphate–sodium bisulphate as initiators, and characterized by FT-IR and EDS. The equilibrium data fit Freundlich isotherm satisfactorily. Adsorption kinetic was fitted with pseudo-second-order. The maximum adsorption capacities for Cs+ by β-CD/BNC in absence and presence of Na+ and Mg2+ were 48.83 ± 0.35, 47.30 ± 0.28, and 42.52 ± 0.85 mg g−1, respectively. Adsorption of Cs+ was suppressed by presence ...
