Analogue Recognition and Chromatographic Behaviors of Molecularly Imprinted Polymer for Protocatechuic Acid
摘要
Abstract
A non-covalent imprinting approach was applied to synthesize protocatechuic acid (3,4-dihydroxybenzoicacid) imprinted polymers (MIPs) in the polar tetrahydrofuran by using methacrylic acid as functional monomer. Byequilibrium adsorption experiments and high performance liquid chromatography (HPLC), the rebinding properties ofthe MIPs to protocatechuic acid (template) and its analogues were evaluated. It was found that the MIPs exhibited highadsorption capability and selectivity for the template and two kinds of absorption sites in the polymer were detected byScatchard curve analysis. The eluents and the mobile phase flow rate had an important influence on the retention of theanalytes on the MIPs column. All of the results showed that the stronger affinity of the MIPs to the template than its an-alogues resulted from the size and shape recognition in the MIPs network based on hydrogen bonding interaction.关键词
