A new conductive polymer nanofiber was prepared by electrospinning of the polymer solution and in situ synthesis. The electrospun polystyrene (PS) fibers were employed as template for the in situ surface polymerization of poly 3, 4-ethylenedioxythiophene (PEDOT). Electrospun nanoﬁbers were utilized as a sorbent in packed fiber solid phase extraction (PFSPE) for selective separation and concentration of As3+, Cd2+, Hg2+ and Pb2+. A SPE coupled with ICP-MS was established for analysis of trace heavy metals in aqueous solution. The extractive recoveries of four metal ions on three nanomaterials, PS, PEDOT, and polystyrene??"dithizone (PS-DZ) nanofibers were compared. PEDOT nanofibers appears better enrichment ability than other two nanofibers, and the average recovery of four metals is 96.3%. It seems that PEDOT was especially suitable for the extraction of heavy metal ions with low concentration in water, which is of great significance in the monitor of trace metals in water sample.
