A novel solid-phase microextraction (SPME) fiber coated with multiwalled carbon nanotubes/polypyrrole (MWCNTs/Ppy) was prepared with an electrochemical method and used for the extraction of pyrethroids in natural water samples. The results showed that the MWCNTs/Ppy coated fiber had high organic stability, and remarkable acid and alkali resistance. In addition, the MWCNTs/Ppy coated fiber was more effective and superior to commercial PDMS and PDMS/DVD fibers in extracting pyrethroids in natural water samples. Under optimized conditions, the calibration curves were found to be linear from 0.001 to 10 ?g mL(-1) for five of the six pyrethroids studied, the exception being fenvalerate (which was from 0.005 to 10 ?g mL(-1)), and detection limits were within the range 0.12-0.43 ng mL(-1). The recoveries of the pyrethroids spiked in water samples at 10 ng mL(-1) ranged from 83 to 112%.
