摘要
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 determination of 7 carbamate pesticides in water by gas chromatography - nitrogen phosphorus detector combined with solid - phase extraction. Methods： The target pesticides in water samples were enrichmented with ENVI - Carb solid phase extraction colunm, and eluted with dichloromethane and acetone（ 1 ＋ 1 ）,and separated with DB- 1701 capillary column and detected with GC -NPD. Results： Seven carbamate pesticides could be well separated, the recovery rates were 82.0% -101.5%, with the relative standard deviation of 2.9% - 10.5%. Conclusion： This method was simple, rapid and sensitive and it can be applied for analysis of carbamate pesticides in water.
