M. published the artcile< Removal of bisphenol A from aqueous media using a highly selective adsorbent of hybridization cyclodextrin with magnetic molecularly imprinted polymer>, SDS of cas: 3290-92-4, the main research area is magnetic molecularly imprinted polymer bisphenol adsorption structural thermodynamical property; adsorption; bisphenol A; molecularly imprinted polymer; water samples; å°?cyclodextrin.
In this study, a unique magnetic molecularly imprinted polymer (MMIP) adsorbent towards bisphenol A (BPA) as a template mol. was developed by bulk polymerization using å°?cyclodextrin (å°?CD) as a co-monomer with methacrylic acid (MAA) to form MMIP MAA-å°¾CD as a new adsorbent. å°?CD was hybridized with MAA to obtain water-compactible imprinting sites for the effective removal of BPA from aqueous samples. Benzoyl peroxide and trimethylolpropane trimethacrylate were used as the initiator and cross-linker, resp. The adsorbents were characterized by Fourier transform IR spectroscopy, scanning electronic microscopy, transmission electron microscopy, vibrating sample magnetometer, Brunauer-Emmett-Teller and X-ray diffraction. 1H NMR spectroscopy was used to characterize the MAA-å°¾CD and BPA-MAA-å°¾CD complex. Several parameters influencing the adsorption efficiency of BPA such as adsorbent dosage, pH of sample solution, contact time, initial concentrations and temperature as well as selectivity and reusability study have been evaluated. MMIP MAA-å°¾CD showed significantly higher removal efficiency and selective binding capacity towards BPA compared to MMIP MAA owing to its unique morphol. with the presence of å°?CD. The kinetics data can be well described by the pseudo second-order kinetic and Freundlich isotherm and Halsey models best fitted the isotherm data. The thermodn. studies indicated that the adsorption reaction was a spontaneous and exothermic process. Therefore, MMIP based on the hybrid monomer of MAA-å°¾CD shows good potential of a new monomer in molecularly imprinted polymer preparation and can be used as an effective adsorbent for the removal of BPA from aqueous solutions
