| 摘 要： | 建立了高效液相色谱-紫外检测-质谱定性法,用于谷物中11种三嗪除草剂(西玛津、阿特拉津、扑灭通、特丁通、莠灭净、扑灭津、特丁津、扑草净、扑莠净、草达津、杀草净)残留量的同时测定。样品经丙酮提取,SCX固相萃取柱净化,用高效液相色谱-紫外检测-质谱法测定,液相外标法定量。对样品前处理和色谱分离条件进行了研究和优化。11种三嗪类除草剂在0.02×10-6～1.0×10-6g.mL-1范围内线性良好,相关系数为0.998 7～0.999 9,在0.02～1.0μg.g-1质量浓度范围内,平均加标回收率在61.6%～111.0%,相对标准偏差为2.4%～6.1%。方法简便、快速,净化效果较好,可同时满足进、出口谷物中多种除草剂残留量的检验要求。

| Abstract: | A high performance liquid chromatography-UVdetection-mass spectrometry qualitative method has been developed for determination of residues 11 triazine herbicides(simazine,atrazine,prometon,terbumeton,ametryne,propazine,terbuthylazine,prometryne,terbutryne,trietazine,dipropetrne) in grain.Triazine herbicides were extracted from grain with acetone and cleaned up with SCX solid phase extraction cartridges.Then triazine herbicides extracted were analyzed by HPLC with ultraviolet and mass spectrometric detection... |
