Abstract: The bisphenol A (BPA) imprinted monolithic precolumn has been prepared by in situ polymerization using 4-vinylpyridine (4-VP) and ethylene dimethacrylate (EDMA) as functional monomer and cross-linker, respectively. The column with good flow-through property was obtained by changing the molar ratio of the porogens (toluene and dodecanol). The selectivity and retention properties of the monolith for the BPA and other phenolic compounds were evaluated. The results show that the hydrophobic and hydrogen-bonding interaction plays important roles in the recognition process. The determination of BPA and other phenolic compounds with on-line solid-phase extraction (SPE) by monolithic precolumn coupled with conventional particulates packed and monolithic reversed-phase columns, respectively, was performed. The method was successfully applied to the analysis of phenolic compounds in river water
