| Abstract: | The fipronil and admire in water sample were determined by gas chromatograph with nitrogen-phosphorus detector（NPD-GC） using dichloromethane as extractant to observe the influence of acid and alkali extraction conditions.The results showed that the good linear ranges were 1.00 mg/L～20.0 mg/L for fipronil and 0.500 mg/L～10.0 mg/L for admire.The detection limits were 0.018 mg/L and 0.004 mg/L（sample volume 200 mL and extractant volume 5 mL）,RSD of parallel standard solution from 12.2% and 5.6%,recoveries of matrix from 79.6% to 90.1% and from 98.5% to 104% for fipronil and admire,respectively. |
