摘要：A facile, low cost, sensitive and environmentally friendly polyaniline (PANI) coating was prepared onto the basalt fibers (BFs) by in situ hydrothermal growth method. PANI functionalized BFs were placed into a poly(ether ether ketone) (PEEK) tube as a fibers-in-tube solid-phase microextraction (SPME) device. The extraction and analysis processes were carried out by connecting it to high performance liquid chromatography (HPLC). Three ultraviolet filters including 2-hydroxy-4-methoxybenzophenone, phenyl salicylate and 2,4-dihydroxybenzophenone were employed as model analytes. Under the optimal extraction and desorption conditions, online in-tube SPME-HPLC analysis method was established and afforded satisfactory enrichment factors (1323–1555), wide linear ranges (0.06–100 μg L−1) with correlation coefficients ranging from 0.9995 to 0.9999, low limits of detection (0.02–0.05 μg L−1) and acceptable extraction repeatability (RSD < 7.8%, n = 6) and preparation repeatability (RSD < 9.7%, n = 3). The proposed method was successfully applied to the determination of the three ultraviolet filters in two environmental water samples.
