摘要：
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 to 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.
