| 摘 要： | 建立了苯醚甲环唑和丙环唑在水稻中的残留量分析方法.样品经丙酮提取后,液-液分配进行净化,用气相色谱电子捕获检测器测定苯醚甲环唑和丙环唑的残留量.结果表明:苯醚甲环唑在稻出水、稻田土壤、水稻稻杆、谷壳和糙米中的最低检出量分别为0.005 mg/L,0.00125、0.0025、0.0025、0.0025 mg/kg,丙环唑的最低检出量分别为0.0001 mg/L,0.00025、0.0005、0.0005、0.0005 mg/kg.测出苯醚甲环唑、丙环唑在不同样品中的平均回收率为80.81%～112.85%和83.71%～112.11%,相对标准偏差为0.74%～6.11%和2.52%～7.29%.

| Abstract: | A method for determining residue of difenoconazole and propiconazole in rice was established.Samples were extracted with acetone,purified on liquid-liquid partition and detected by gas chromatography with electron-capture detector.Detectable limits of difenoconazole residue in water,soil,plants,rice hulls and rice were 0.005 mg/L,0.001 25,0.002 5,0.002 5,0.002 5 mg/kg,respectively,and detectable limits of propiconazole residue were 0.000 1 mg/L,0.000 25,0.000 5,0.000 5,0.000 5 mg/kg.The recoveries of difeno... |
