[Determination of chlorophenols in drinking water by headspace solid phase microextraction and gas chromatography].
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%.


CONCLUSIONS
The method was simple, sensitive and without solvent, which was an ideal method for determination of chlorophenols in drinking water.
