摘　　要：[方法]研究了氟硅唑在苹果上的残留分析方法。样品用丙酮-水(体积比70∶30)混合溶液提取,液液分配后,气相色谱-氮磷检测(NPD)法测定。[结果]最小检出量为6.0×10-11 g,最低检测质量浓度为1.0×10-2 mg/L,平均回收率为90.9%～104.7%,相对标准偏差为4.7%～8.8%。[结论]方法简便、快速、准确度高、精密度好。[Methods] A method was studied to determine the residue of flusilazole in apple.residues of flusilazole were extracted from samples with acetone：water（70：30,by vol）,after liquid-liquid partition,determined with gc-NPD.[Results] The minimum detectable limit was 6.0×10-11 g,and minimum determination concentration was 1.0×10-2 mg/l,the average recovery rate was 90.9-104.7%,the relative standard deviation was 4.7-8.8%.[Conclusions] The method was fast,simple and sensitive with good accuracy.
