摘　　要：以气相色谱串联质谱法(GC-MS/MS)多反应监测(MRM)方式进行定量和定性分析建立了土壤中除草剂莠去津、塞克津、2,4-D丁酯残留含量的联合测定方法。结果表明,本方法有效地降低了样品复杂基质带来的干扰,简化了分析步骤。采用外标法定量测得回收率为73%～104%,标准偏差为5.9%～11.5%,方法的回收率和线性关系结果令人满意,实验证明,该方法快速、准确、灵敏度高,适用于土壤中除草剂莠去津、塞克津、2,4-D丁酯残留含量的联合检测。Gas chromatography-tandem mass spectrometry with the mode of MRM was used to determine residual content of atrazine,metribuzin,and 2,4-D-butyl ester in soil.This method can effectively lower the interference from complex factor,simplify analytical procedure.The external reference method was determined the recovery of three pesticides about 73%-104%,and the values of RSD of the three pesticides were 5.9%-11.5%.The results of recovery and linearity were satisfactory.The method is fast,accurate and high sensitivity,and it is suitable for united determination of residual content of atrazine,metribuzin and 2,4-D-butyl in soil.
