The natural anion exchange property of conducting polymer polypyrrole (PPY) was examined using solid phase microextraction (SPME) methods. Our preliminary results demonstrated that the anion exchange property of PPY could be utilized for direct SPME of anionic species from aqueous solutions without derivatization. This paper presents the first example of coupling SPME to ion chromatography (IC).
