建立了气相色谱法测定香蕉果肉、全果和土壤中苯醚甲环唑残留量的分析方法。实验结果表明：添加量为0．02～2．0mg／kg时．果肉、全果和土壤中的平均回收率分别为：86．88％-98．52％、83．80％-96．01％和94．00％～97．27％．相对标准偏差分别为2．77％～5．74％、3．98％-6．11％和2．76％-5．32％，方法的最小检出量为2．0×10^-12g．最低检出浓度为0．002mg／kg。方法快速、灵敏度高、重现性好，具有较好的准确度和精确度．可用于环境系统中的苯醚甲环唑的残留检测分析。

An analysis method for determination of difenoconazole residue in banana and soil by using GC was established. When the content of difenoconazole was 0.02 mg/kg, 0.2 mg/kg and 2.0 mg/kg, the average recoveries of difenoconazole in pulp, whole banana and soil were 86.88%-98.52% , 83.80%-96.01% and 94.00%-97.27%, respectively. The corresponding relative standard deviations were 2.77%-5.74%, 3.98%- 6.11% and 2.76%-5.32%, respectively. The limit of detection of difenoconazole was 2.0×10^-12 g and the limit of quantification of method for difenocon...
