中文摘要	应用固相萃取(SPE)-超高效液相色谱-串联质谱法(UPLC-MS/MS)建立了水中27种三嗪类除草剂的分析方法.通过对固相萃取柱、淋洗液和色谱柱流动相等的优化,确定以Oasis HLB固相萃取柱、0.1%甲酸-乙腈(2:8,V/V)为淋洗液、0.1%甲酸-乙腈(6:4,V/V)为流动相做水样预处理.在最优条件下,目标物在水中回收率为79.1%-129.2%,相对标准偏差(RSDs)在8.8%-14.3%,线性范围均在1-2000 mug?L~(-1),各目标物标准品在UPLC-MS/MS系统中有效的线性相关系数(R~2)为0.999以上.该方法具有检测限低、回收率高等优点,经实际样品测试,可适用于水中27种三嗪类除草剂残留的同时检测.
英文摘要	An analytical method for the simultaneous determination of 27 triazine herbicides in water samples was developed using solid phase extraction-ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). An Oasis HLB solid phase extraction cartridge, water containing 0.1% formic acid-acetonitrile (2:8,V/V) as washing solution, water containing 0.1% formic acid-acetonitrile (6:4,V/V) as the mobile phase were selected for sample pretreatment and chromatographic separation. Based on the optimized sample pretreatment procedures and separation condition, the target recoveries ranged from 79.1% to 129.2% in water with the relative standard deviation (RSDs) ranging from 8.8% to 14.3%. The linear range was from 1 to 2000 mug?L~(-1) with correlation coefficients (R~2) above 0.999. The method can be applied to simultaneous determination of 27 triazine herbicides in surface water because of low detection limit and high recovery.
