dc.description.abstractA solid-phase microextraction (SPME) fiber coated with single walled carbon nanotubes (SWCNTs) was prepared by electrophoretic deposition and treated at 500 degrees C in H-2 stream. In order to evaluate the characteristics of the obtained fiber, it was applied in the headspace solid-phase microextraction (HS-SPME) of benzene, toluene, ethylbenzene and xylenes (BTEX) from water sample and quantification by gas chromatography with flame ionization detection (GC-FID). The results indicated that the thermal treatment with H-2 enhanced the extraction of the SWCNTs fiber for BTEX significantly.Thermal stability and durability of the fiber were also investigated, showing excellent stability up to 350 degrees C and life time over 120 times. In the comparison with the commercial CAR-PDMS fiber, the SWCNTs fiber showed similar and higher extraction efficiencies for BTEX. Under the optimized conditions, the linearity, LODs (S/N = 3) and LOQs (S/N = 10) of the method based on the SWCNTs fiber were 0.5-50.0, 0.005-0.026 and 0.017-0.088 mu g/L, respectively. Repeatability for one fiber (n = 3) was in the range of 1.5-5.6% and fiber-to-fiber reproducibility (n = 3) was in the range of 4.2-8.3%. The proposed method was successfully applied in the analysis of BTEX compounds in seawater, tap water and wastewater from a paint plant. (C) 2010 Elsevier B.V. All rights reserved.zh_CN
