氧化乐果残留量的测定方法,国内未见研究报导。我们对氧化乐果在小麦中残留量的测定进行了初步探讨。采用丙酮提取、中性氧化铝和活性炭混合柱净化、薄层层析酶抑制工作曲线法测定。得到了较为满意的结果。一、主要仪器和试剂 1.仪器振荡器:ZD—2型高速组织捣碎机;2000—16000转/分离心机:4000转/分 K。D浓缩器层析缸:7×15×25厘米层析板:12×20厘米玻璃板微量注射器:10微升、50微升喷雾器:50毫升层析柱:1.5×30厘米
Omethoate determination of residual methods, no domestic research reports. We conducted a preliminary study on the determination of omethoate in wheat. Using acetone extraction, neutral alumina and activated carbon mixed column purification, thin layer chromatography enzyme inhibition curve. Have been more satisfied with the results.
