A new method based on solid phase microextraction(SPME), coupled with GC/FID, has been developed for the determination of PCE and TCE in water samples. The experimental parameters affecting the SPME process (i.e, kinds of fibers, extraction time, desorption time, extraction temperature, volume ratio of sample to headspace, salt addition, and magnetic stirring) were optimized. The coefficients of determination (R2) for PCE and TCE were 0.9951 and 0.9831, respectively when analytes concentration ranges from 10 to 300㎍/L. The relative standard deviations were 3.4 and 2.1% for concentration of 10㎍/L(n=5), respectively. The detection limits of PCE and TCE were 0.5 and 1.3㎍/L, respectively.
