【摘要】 建立了高效液相色谱仪检测蔬菜中阿维菌素的残留分析方法。用石油醚-丙酮(体积比8∶2)提取大白菜样品中残留的阿维菌素,石油醚萃取,经弗罗里硅土和活性炭柱净化,高效液相色谱法(二极管阵列检测器)进行测定,以甲醇-水(体积比86∶14)为流动相,流速1.0mL/min,检测波长245nm。方法的回收率为80.27%～99.54%,相对标准偏差在2.1%～4.8%之间。更多还原

【Abstract】 A quantitative high performance liquid chromatography method has been studied for the determination of abamectin in cabbage.Abamectin was extracted from the samples by petroleum ether-acetone(8:2,by vol),and further extracted with petroleum ether by liquid-liquid extraction,purified with florisil and activated carbon column,and determined by high performance liquid chromatography with diode-array detector.The mobile phase was methanol-water(86:14,by vol),with the flow rate 1.0 mL/min,and the wavelength was 245 nm.The results showed that the average recoveries ranged from 80.27 to 99.54%,with a coefficient variation between 2.1 and 4.8%.更多还原
