Abstract Linear ionic liquid bonded to fused silica and its application as a solid-phase microextraction fiber for the extraction of bisphenol A (BPA) from water samples were studied. Afteroptimization of microextraction conditions (15 mL sample volume, extraction time of 40 min, extraction temperature of 30± 1°C, 300 μL acetonitrile as the desorption solvent, and desorption time of 7 min), the fiber was used to extract BPA from packed mineral water, followed by HPLC–UV on an XDB-C18 column (150 × 4.6 mm id, 3.5 μm particle) with a mobile phase of acetonitrile–water (45 + 55%, v/v) and flow rate of 1 mL . min−1). A low LOD (0.20 μg. L−1) and good linearity (0.9977) in the calibration graph indicated that the proposed method was suitable for the determination of BPA.
