ResumoAn effective and reliable analytical method based on molecularly imprinted solid-phase extraction (MI-SPE) and high-performance liquid chromatography with photodiode array detector was developed to simultaneously determine four phenolic compounds: bisphenol A, 2-phenylphenol, tert-octylphenol and nonylphenol.A molecularly imprinted polymer that can selectively recognize bisphenol A and alkylphenols was developed.A bulk polymerization method using bisphenol A as a template, acrylamide as functional monomer, ethylene glycol dimethacrylate as the cross-linking agent, acetonitrile as porogenic solvent and 1,1'-azobis(cyclohexanecarbonitrile) as initiator was applied.This polymer was applied for isolation and preconcentration of these phenolic compounds from surface water's sample of Opole Region (Odra River, Nysa Kłodzka River, Mała Panew River and Turawa Lake).Bisphenol A and 2-phenylphenol were found in all water samples.Concentration of these compounds ranged 0.011-1.046µg/mL and 0.020-0.410µg/mL, respectively.Nonylphenol and tert-octylphenol were not detected in any samples.
