摘    要:采用H2SO4加入法改变了酸性除草剂在水中的存在状态,对碱性活化点的存在与消除进行了分析,同时对不同试剂的萃取效率进行了对比,建立了衍生气相色谱-质谱法测定水中10种氯代酸性除草剂的方法。化合物检出限均低于10.0 ng/L,回收率范围为60%~120%。

关 键 词:碱性活化点  衍生  氯代酸性除草剂  气相色谱-质谱

Abstract:By changing existing form of acid herbicide with adding sulfuric acid,existing and eliminating of activated points on alkaline were analyzed,and comparison of different reagents,a derivative gas chromatography-mass spectrometry which can detect 10 kinds of acid herbicides in water is developed.Its detection limit can be below 10.0 ng/L and recoveries are between 60% and 120%.
Keywords:Activited points of alkaline  Derivative  Chloro-substituted acid herbicide  Gas chromatography-mass spectrometry
