Prepare mono-6-O-aminoethyl-β-cyclodextrin ( 6-EA-β-CD ) and mono-6-O-( p-toluenesulfonyl)-β-cyclodextrin ( 6-OTs-β-CD ) . The ethylamine-bridged β-cyclodextrins was synthetized by 6-OTs-β-CD and 6-EA-β-CD under specific conditions. FTIR, NMR spectroscopy and elemental analysis were employed to confirm the reliability of the newly synthetic bis(β-cyclodextrin) . Scanning electron microscope was used to characterize the surface morphology of the material. Study on bridged β-cyclodextrins’ s adsorption proper-ties of Thorium ions under different conditions. Experiments show that:the adsorption of thorium using the material prepared can achieve equilibrium within 60 minutes at room temperature under the condition of pH=4,the adsorption capacity is 10. 49 mg/g.
