Preparation of β-Cyclodextrin Polymer by Inverse-Phase Suspension Polymerization and its Capability for Phenol Removal

Abstract:

β-Cyclodextrin polymer were prepared by inverse-phase suspension polymerization using epichlorohydrin (EPI) as crosslinker. The architecture has been characterized by Fourier transform infrared spectra (FT-IR) and thermogravimetric analysis (TGA), which confirmed that cyclodextrin polymer have been synthesized successfully. β-Cyclodextrin polymer (EPI-CD) can interact with a variety of hydrophobic compounds to form inclusion complexes, such as phenol. Experimental results indicated that the adsorption reached to 58.51umol/g under the initial concentration of 120mg/L at 298K. The adsorption isotherm was fitted to the Langmuir and Freundlich models. From the experimental data, it may be inferred that EPI-CD polymer was an effective adsorbent for the removal of phenol in wastewater treatment.
