Hollow fiber supported liquid membrane (HFSLM) was applied for the extraction of bisphenols (BPs), including bisphenol S, bisphenol AF, tetramethylbisphenol A, tetrachlorobisphenol A and tetrabromobisphenol A from water samples. The undecane solution of 1.0% (m/v) tri-n-octylphosphine oxide was supported on the pores of the polypropylene hollow fiber membranes (280 mm i.d., 50 mm wall thickness, 0.1 mm pore size, 60 cm length) to form a liquid membrane. The lumen of the hollow fiber membranes was then filled with 0.3 M NaOH as an acceptor to prepare the extraction device, which was placed into a 500 mL water sample (donor) adjusted to pH 4.0 with HCl. After shaking at 200 rpm for 180 min, the acceptor ($30 mL) was collected and injected into the high performance liquid chromatography system for the determination of the BPs. The proposed HFSLM method provided good enrichment factors (1370-2138), low detection limits (0.1-
mg L
À1) and good repeatability (RSD ¼ 2.6-8.8%, n ¼ 5). The proposed method was applied to determine the five target BPs in waste water, tap water, river water and lake water samples with satisfactory spiked recoveries (68.6% to 134%) at 0.5 and 1 mg L À1 spiking levels, demonstrating the practicality of the proposed method for the determination of BPs in environmental water samples.
