[Study on the method for determination of pentachlorophenol in water].
OBJECTIVE
To establish a method for sensitive and rapid determination of pentachlorophenol (PCP) in different water.


METHODS
Based on the actual national standard detection method of PCP, gas chromatographic conditions and quantitative method were modified and optimized. The modified method was used for the determination of pentachlorophenol in samples from natural water, output water and tap water.


RESULTS
A modified method for the detection of PCP in drinking water samples was developed with the conditions of gas chromatography as follows: the capillary column was used for separation and tribromophenol (TBP) as internal standard for quantification, the linear range were 0.1 - 10 microg/L, and the correlation coefficient was 0.9999. The limit of detection was 4.5 ng/L. Recoveries were between 90.1% and 98.4%, and RSD was less than 4.1% .


CONCLUSIONS
The proposed method is a sensitive and accurate method for trace analysis of PCP in different water.
