| 摘 要： | 为提高烟草中农药残留量的检测效率,建立了一种快速测定二硫代氨基甲酸酯类农药的方法.在密闭系统中,试样中的二硫代氨基甲酸酯在加热、超声条件下与还原性酸溶液反应,分解产生的二硫化碳经过异辛烷吸收后用气相色谱/质谱联用法(GC/MS)检测,以二硫化碳的含量表示二硫代氨基甲酸酯残留量.结果表明:方法的回收率在90.4%～106...

| Abstract: | A method was presented for the analysis of dithiocarbamate pesticide residues in tobacco,in which tobacco was put into a closed-conical flask,the residues of dithiocarbamate pesticides in tobacco were extracted and hydrolyzed to CS2 under ultrasonic conditions,then CS2 trapped in a layer of iso-octane overlaying the reaction mixture was taken for gas chromatography-mass spectroscopy analysis.The recoveries ranged from 90.4% to 106.0% with the relative standard deviations(RSD) of 3.2% to 9.5% and the limit o... |
