摘要：

A poly(β-Cyclodextrin)/bentonite composite (β-CD/BNC) were characterized by N2–BET measurement, scanning electron microscopy, energy dispersive spectrometer, fourier transform infrared spectroscopy, thermogravimetric analysis and X-ray photoelectron spectroscopy. Its synthesis mechanism of graft polymerisation was expounded. The maximum sorption capacities of Cs+ onto β-CD/BNC in absence and presence of Cl− and CO3 2− were 48.83mgg−1, 48.90mgg−1, and 46.19mgg−1, respectively. The effect of Cl− and CO3 2− on Cs+ adsorption was not obv...
