摘　　要：建立加速溶剂萃取-高效液相色谱质谱法检测土壤中三唑醇、腈菌唑、三唑酮、戊唑醇、腈苯唑和氟菌唑残留的方法。6种三唑类杀菌剂在3.00~200μg·L^(-1)质量浓度范围内线性关系良好,样品加标回收率为87.5%~103.5%,6次测试结果相对标准偏差均小于5%。本方法操作简便快捷,测试结果准确可靠,检出限低,适用于土壤中痕量三唑类杀菌剂残留的检测。An accelerated solvent extraction and high performance liquid chromatography-mass spectrometry method was developed for the determination of residues of triazolol,nitrile,triazolone,pentazolol,nitrile and flumidazole in soil.The linear relationships of the six triazole fungicides were good in the concentration range of 3.00~200μg·L^(-1),and the recoveries of the spiked samples were 87.5%~103.5%.The relative standard deviations of the six tests were all less than 5%.The method is simple and fast,the test results are accurate and reliable,the detection limit is low,and it is suitable for the detection of trace triazole fungicide residues in soil.
