What is Enhancing Extraction Rate in Solid-phase Microextraction by Using Nano-structured Polyaniline Coating about?

## Abstract The decrement of equilibrium extraction time without losing extraction efficiency in solid‐phase microextraction (SPME) was achieved using nano‐structured coating. Polyaniline (PANI) was used as an extraction phase for the comparison of extraction capacity and equilibrium extraction time of nano‐ and micro‐structured coatings. Polychlorinated biphenyls (PCBs) were used as model compounds to examine the extraction properties of nano‐ and micro‐structured coatings. The results revealed that nano‐structured PANI coating showed higher extraction rate and shorter desorption time than micro‐structured coating, because of the larger surface area. In order to evaluate the extraction capability of prepared nano‐structured PANI coating, headspace‐SPME method was used for the determination of PCBs in sediment samples by GC‐electron capture detector. The proposed method was validated using the certified reference material.
