| 摘 要： | 利用超高效液相色谱-串联质谱技术，建立了检测土壤样品中烟嘧磺隆残留量的分析方法。土壤样品用水和乙腈的混合溶液振荡提取，用UPLC—MS／MS测定。烟嘧磺隆在土壤中的平均回收率为83．1～106．2％，RSD为3．2～8．6％。该分析方法最低定量浓度为1．0μg／kg。该方法具有灵敏度高、操作简单、有机溶剂用量少等特点，可用于土壤样品中烟嘧磺隆的检测。

| Abstract: | The analysis method of nicosulfuron in soil was established using UPLC-MS/MS.The soil sample were extracted by the mixture of water and acetonitrile then determined by UPLC-MS/MS.The average recoveries rate and RSD of nicosulfuron in soil were 83.1～106.2% and 3.2～8.6% respectively.The LOQ of the analysis method was 1.0μg/kg.The method was sensitive,simple and less use of organic solvent so that reliable to analysis nicosulfuron residues in soil. |
