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 crosslinker in anhydrous dimethyl sulfoxide (DMSO). The obtained polymer particles were characterized by infrared spectrophotometry (IR) and scanning electron microscopy (SEM). The performance of the β-CD-MIP was evaluated in terms of selectivity, adsorption capacity and binding characteristics. The β-CD-MIPs exhibited better recognition and selectivity for Bisphenol A. The rebinding ability of the β-CD-MIPs towards Bisphenol A was much higher than analogs such as bisphenol C (BPC) and p-nitrophenol (p-NP). The results of the binding experiments in aqueous solution were fitted by Freundlich and Langmuir model, and indicated that the adsorption reaction was exothermic, and the low temperature was favorable for adsorption.
