| Abstract: | Eight organochlorine pesticides were determined by gas chromatograph with electron capture deteetor（ECD） after pre-treatment by liquid-liquid extraction with n-hexane. The results showed that the detection limits of the method for 8 pesticides were in the ranges of 1.6 × 10^-3 μg/L-3.3 × 10^-3μg/L, the recoveries were 82.1%-106.1% and showed good linear in the range of 1/μg/L- 100/μg/L. The method provides the advantages of low detection limits, good accuracy and precision, simple operation and is suitable for analysis of organochlorine pesticides in drinking water. |
