    Abstract:
    OBJECTIVE: To study the method for determination of chlorophenols in drinking water by headspace solid phase microextraction and gas chromatography. METHODS: Chlorophenols in water samples was extracted using optimized SPME technology, separated by HP-5 chromatigraphic column and the concentration of chlorophenols was determined by electron capture detector (ECD). RESULTS: The detection limit of MCP, DCP, TCP, PCP were 60.0 microg/L, 2.64 microg/L, 0.15 microg/L and 0.84 microg/L. The correlation coefficient(r) were 0.999, 0.997, 0.997, 0.995. When adding standard material of MCP, DCP, TCP, PCP at low, middle, high concentrations, the recovery rates were 95.3% - 107%, 93.6% - 102%, 92.4% - 102%, 91.5% -99.1% and the RSD (n = 6) were 1.0% - 8.1%,1.6% - 6.6%, 2.9% - 8.6%, 2.0% - 8.2%. CONCLUSION: The method was simple, sensitive and without solvent, which was an ideal method for determination of chlorophenols in drinking water.
