Abstract

A perfluorooctanesulfonic acid-doped polyaniline (PFOS-doped PANI) directly electrodeposited onto stainless steel was employed as a solid-phase microextraction (SPME) fiber. Commercial SPME fibers were chosen to compare with the PFOS-doped PANI through extraction of phenols and polybrominated diphenyl ethers (PBDEs). Excellent extraction efficiency of this fiber was demonstrated, indicating its good affinity for both non-/less polar and polar compounds. To achieve maximum response, influential parameters affecting the extraction efficiency were optimized by full-factorial experimental designs. Under the optimized conditions, the analytical features for PBDEs were estimated. The calibration curve was linear approximately 3 orders of magnitude for the target analytes, with linear correlation coefficients greater than 0.99. Detection limits in the range of 0.1-0.2ng/L were obtained. Repeatability (n=5) was in the range of 4.5-8.3%. The results suggest that the proposed fiber can be applied for the determination of trace PBDEs in environmental water and expected to be extended to other analytes and matrices.
