Selecting Reorganization of Bisphenol A by Molecularly Imprinted β-Cyclodextrin Polymer in Aqueous Solution

doi:10.3969/j.issn.0251-0790.2012.09.041

Abstract

Abstract:

Molecularly imprinted polymers (MIP) were synthesized by mixing bisphenol A(BPA) as the template, β-cyclodextrin as the monomer and hexamethylene diisocyanate (HDI) as the cross-linker in anhydrous dimethyl sulfoxide (DMSO). The obtained polymer particles were characterized by infrared spectrophotometer (IR) and scanning electron microscopy (SEM). The results of equal and unequal opportunity competition adsorption between bisphenol A(BPA) and bisphenol C(BPC) confirmed that β-CD-MIPs exhibited much better recognition and selectivity for BPA than BPC. The parameters of thermodynamics for the adsorption process verified the adsorption reaction was spontaneous and exothermic process and low temperature was favorable for adsorption.

Key words: Molecular imprinted polymer, β-Cyclodextrin, Bisphenol A, Specific selectivity, Adsorption
