Abstract: A molecular imprinted polymer of bisphenol A(P-BPA) was prepared. The eluting efficiencies of different solvent systems for eliminating the template, from the P-BPA Were investigated. The, P-BPA showed-specific recognition characteristics for molecules with a bisphenolic structure such as bisphenol A, 4,4-bis (4-hydroxyphenyl)valeric acid and phenolphthalein. The possibility to use bisphenol. A-imprinted Polymer as a solid- phase extraction material was also studied. The best binding buffer was found 16 be acetonitrile containing 0.05% (volume fraction),of Tween 20, and acetonitrile-ethanol solution containing 0.5% (volume fraction) diethanolamine was found to be the optimal eluting solvent.
Template and target information: bisphenol A, BPA
