Synthesis and Adsorption Property of Bitertanol Molecularly Imprinted Polymer
摘要
Abstract
A bitertanol molecularly imprinted polymer (BMIP) was prepared by the method of bulk polymerization under different ratios between template molecular and functional monomer,using bitertanol as template molecule and methacrylate acid (MAA) as functional monomer and its specifie recognition ability was studied.The influence of different pore-foaming agents on the interaction between template molecular and functional monomer was investigated.The effect of the prepared polymer using different ratios template molecular and functional monomer on the adsorption content of bitertanol was also studied.Adsorption property of bitertanol was examined by static adsorption test and analyzed by Scatchard analysis.The maximum absorption wavelength of bitertanol by using acetonitrile and tetrahydrofuran as pore-foaming agents showed 5 nm and 6 nm red shifts,respectively,and its absorption intensity increased.Scatchard analysis showed that bitertanol temphte molecule and functional monomer MAA formed two types of binding sites and the dissociation constants of the binding sites were 3.16 mmol/L and 107.53 mmol/L,respectively.Tetrahydrofuran and acetonitrile were more suitable for the preperation of BMIP.The molecularly imprinted polymer can be used as the separation media of bitertanol with high affinity and good specific recognition ability.关键词
