摘要
就粮谷（大米、小米、玉米）中农药残留量的检测方法,进行了改进性实验。应用超临界流体萃取气相色谱法快速测定拟除虫菊酯残留量。整个运作分析时间小于1h。其结果与传统测定法相比,具有速度快、效率高、应用范围广、可选择萃取、不污染环境等特点。在粮谷食品分析中显示了极大的优越性。对于掌握粮谷农残状况、控制农药使用方面,将发挥重要作用。
An improved experiment -was engaged for test method of pesticide residue in grain . The supercritical fluid extraction gas chromatography was used to determine quickly. Pseudopyrethroester residue amount. All operating time was less than 1 hour.The result, compared to the traditional measurement method, possesses the character of high speed and effectiveness, widespread application, selectable extraction, and nonenvironmental pollution, and shows extreme advantage in grain analysis. It will play a key role to mastering pesticide residue condition and controlling the application amount of pesticides.
