Preparation of Magnetic Chitosan-β-Cyclodextrin Polymer and its Adsorption for Thallium (III) in Aqueous Solution

Abstract:

Magnetic chitosan bonded β-cyclodextrin polymer was prepared, and its metal ion binding was studied using the batch static tests for thallium removal. The results indicated that magnetic chitosan-β-cyclodextrin polymer (MCS-CD) showed a high efficiency for the removal of thallium, the experiment data fitted well to the pseudo second-order kinetic model, the maximum adsorption capacity of 2.154mgg-1 was obtained according to the isothermal data.
