Selective Adsorption and Molecular Recognition by a Molecularly Imprinted Polymer: Kinetic Study and Analysis

Abstract

Abstract This article presents an original work aiming at kinetically surveying the substrate‐selective mechanism from a molecularly imprinted polymer. With Bisphenol A (BPA) as the template, the imprinted polymer was prepared. The result indicates that the imprinted polymer presents a much more complicated sorption toward the template than toward its analogue. The rate constant in the case of the template appears to be a function of coverage degree. There are also significant deviations from the idealized Langmuir model. Related information indicates that these logically can be a result from the induced molecular memory within the binding framework, which makes the polymer capable of selectively adsorbing the imprint species.
