| 摘 要： | 目的建立稻田水中莠去津及其代谢物去乙基莠去津（DEA）、去异丙基莠去津（DIA）和双去烃基莠去津（DDA）的灵敏的气质联用分析方法。方法稻田水样品用GDX501大孔树脂进行固相萃取,萃取物用N,O-双三甲硅烷基乙酰胺（BSA）进行三甲硅烷基衍生化,衍生物用选择离子监测的气质联用法分析。结果稻田水中4种分析物的检出限和测量限都不高于2ng/mL。结论该方法可用于刑事案件中莠去津毁坏稻田案件的检验。

| Abstract: | Objective To establish an analytical method of atrazine and its metabolites[deethylatrazine(DEA),deisopropylatrazine(DIA)and didealkyl atrazine(DDA)]in water by using gas chromatography and mass spectrometry.Methods The water samples were extracted by solid phase extraction technique using GDX501 porous resin.The extracts were BSA derivatized,and then analysed by gas chromatography mass spectrometry in the selected ion monitoring mode.Results The limit of detection(LOD) and the limit of quantitation(LOQ) of... |
