目的:建立应用气相色谱-氮磷检测器结合固相萃取测定水中7种氨基甲酸酯农药的方法。方法:水样经ENVI-Carb固相萃取柱富集,以二氯甲烷+丙酮(1+1)洗脱,采用DB-1701毛细管柱和氮磷检测器进行检测。结果:7种氨基甲酸酯农药在DB-1701毛细管柱上均能得到很好分离,回收率在82.0%～101.5%,相对标准偏差为2.9%～10.5%。结论:本方法简便、快速、灵敏,可用于水中氨基甲酸酯农药的检测。
Objective: To establish a method for the determination of seven carbamate pesticides in water by gas chromatography-nitrogen / phosphorus detector combined with solid-phase extraction. Methods: The water sample was enriched by ENVI-Carb solid phase extraction column and eluted with dichloromethane + acetone (1 + 1). DB-1701 capillary column and nitrogen and phosphorus detector were used for detection. Results: Seven kinds of carbamate pesticides were well separated on the DB-1701 capillary column. The recoveries ranged from 82.0% to 101.5% with relative standard deviations of 2.9% -10.5%. Conclusion: The method is simple, rapid and sensitive and can be used for the determination of carbamate pesticides in water.
