Scheme 6.
Synthesis route of surface-imprinted core-shell magnetic beads and their application for extraction of bisphenol A. (a) Fe3O4 magnetite particles synthesis by a co-precipitation method followed by silica coating and functionalization with chloromethyl-phenyl groups; (b) β- cyclodextrin modified with an epoxy bond; (c) 4-vinylpyridine and β- cyclodextrin used as binary functional monomers for the synthesis of the MIP for bisphenol A.
