氧乐菊酯、乐菊酯(菊乐合酯)、菊敌是目前常见的混配农药。它们分别由有机磷农药氧化乐果、乐果、敌敌畏与拟除虫菊酯类农药杀灭菊酯以不同比例科学配制而成,其毒性较大。对上述混配农药的同时检测技术,未见文献介绍,笔者参阅了有关文献,经多次试验研究,建立了氧乐菊酯、乐菊酯、菊敌农药薄层一板检出技术。本法所用仪器简便,具有定性准确、快速,灵敏度较高、经济实用等优点。一方法原理样品经氯仿提取,在硅胶 G 板上点样、展开、在
Lexithionate, Delthrion (Chrysanthemum synthesis ester), Chrysanthemum is currently common mixed pesticides. They were respectively organophosphorus pesticide oxidation dimethoate, dimethoate, dichlorvos and pyrethroid insecticide pyrethrins in different proportions scientifically formulated, its toxicity. The above simultaneous detection of pesticides mixed technology, no literature introduction, the author refers to the relevant literature, after many trials and studies, the establishment of the Lexithromycin, Delthrin, Daisy Pesticide TLC plate detection technology. The instrument used in this method is simple, with the advantages of qualitative accuracy, fastness, high sensitivity, economy and practicality. A sample of the principle of chloroform extraction method, the G spot on the silica gel plate, expand, in
