在建立的戊唑醇残留分析方法中,小麦样品用丙酮为萃取溶剂,加水10 mL,机械振荡法提取,提取液用石油醚液液分配2次,中性氧化铝层析柱净化,气相色谱(GC-NPD)检测。小麦中戊唑醇的添加浓度分别为0.025、0.05和0.5 mg.kg-1,其回收率分别为73.98%～82.86%、81.21%～95.38%和81.51%～97.98%,变异系数为5.74%～9.33%。结果满足农药残留分析的要求。 In the established tebuconazole residue analysis method, the wheat sample was extracted with acetone as the extraction solvent, 10 mL of water was added and the mixture was extracted by mechanical shaking. The extract was partitioned twice with petroleum ether, purified by a neutral alumina column and analyzed by gas chromatography (GC-NPD) test. The concentrations of tebuconazole in wheat were 0.025,0.05 and 0.5 mg.kg-1, respectively, and the recoveries were 73.98% -82.86%, 81.21% -95.38% and 81.51% -97.98%, respectively, and the coefficients of variation were 5.74% 9.33%. The results meet the requirements of pesticide residue analysis.
