| Abstract: | A method has been developed for determination of 25 organochlorine pesticides in soil and sediment using ultrasonic wave extraction - capillary gas chromatography. The detection limit was 0. 079- 1.2 μg,/kg, the recovery was 73.1% - 126. 5% and the RSD was 3.3% - 9. 7%. The experimental results showed that this method had high sensitivity, high precision, simple and rapid, thus was suitable for determining the organochlorine pesticides in soil and sediment. |
