采用二氯甲烷萃取水样，气相色谱-串联质谱法同时测定水中有机磷农药和甲萘威。试验表明：方法在20．0μg/L ～1000μg/L范围内，各目标化合物线性良好；方法检出限为0．004μg/L～0．01μg/L；对实际水样进行3个质量浓度水平的加标回收试验，回收率在71．8％～94．5％之间，RSD为3．7％～8．5％，满足水中痕量有机磷农药和甲萘威的测定要求。

A method of gas chromatography coupled with triple quadrupole mass spectrometry was estab-lished for determining organophosphorus pesticides and carbaryl in water.The experimental results showed that all the target compounds had good linear relations in the range of 20.0 μg/L~1 000 μg/L.The method limits of detection were 0.004 μg/L~0.01 μg/L.The recoveries of the target compounds ranged from 71.8% to 94.5%and the RSDs were between 3.7% ~8.5% for three concentrations of 0.02 μg/L,0.05 μg/L and 0.1 μg/L. The method could meet the requirements for determination of trace organophosphorus pesticide and carbaryl in water samples.
