摘  要:
确立香蕉中戊唑醇残留检测方法,用丙酮∶水(60∶5,V∶V)为萃取溶剂,液液分配后浓缩至近干,定容后用气相色谱(GC-NPD)测定。戊唑醇的最小检出量为1×10-11g,最低检测浓度为0.01 mg.kg-1。香蕉中添加浓度为0.025、0.05、0.5 mg.kg-1,其回收率分别为98.12%~109.23%、70.37%~99.57%和78.13%~94.53%,变异系数分别为5.55%、17.93%和9.58%。该方法的准确度和灵敏度满足农药残留分析的要求。

摘  要:
A procedure involving an extraction and cleaning up steps and further gas chromatographic analysis with NPD to determine residues of tebuconazole in banana is proposed.Residues of tebuconazole were extracted from banana with acetone,and cleaned up with petroleum ether by liquid-liquid partition.The methods are validated with fortified samples at different concentration levels(0.025~0.5mg·kg-1).Average recoveries ranged from 70.37% to 99.57% with relative standard deviations between 5.55% and 17.93%.Limit of detection is 0.01mg·kg-1.The proposed method can be considered as an appropriate method for monitoring tebuconazole in banana.
