This article presents a fully-conceived work aiming at designing a highly selective sorbent by molecular imprinting. Based on the template-monomer strategy, the imprinted polymer was prepared by using bisphenol A (BPA) dimethacrylate as the polymerisable monomer. The binding framework was generated by releasing BPA from the polymer. Adsorption tests indicated that the prepared polymer can discriminate BPA well from its analogue dihydroxybenzophenone, so as to adsorb more of the former and less of the latter. Theoretical simulation additionally shows that adsorption by this polymer fits the Freundlich and Temkin models well, but not the Langmuir model. Related information indicates that these observations can be a result of induced molecular memory from the imprint.
