摘　　要：采用二氯甲烷萃取水样,气相色谱一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.
