本文介绍了分离艾氏剂、狄氏剂、γ-666、马拉硫磷、对硫磷、五氯苯酚和氯丹七种农药的薄层色谱法。将上述七种农药溶于苯中,用10 μl注射器在薄板上点样,浓度为20 ppm。薄板用烘箱干燥后,放在下列溶剂系统中展开,苯:环己烷:正己烷:二甲苯:甲基环己烷:甲苯(50:50:50:50:50:50)。展开待干燥后喷以1%(V/V)联甲苯胺丙酮溶液。再用热空气干燥,
This article describes the separation of aldrin, dieldrin, γ-666, malathion, parathion, pentachlorophenol and chlordane seven kinds of pesticides by thin-layer chromatography. The above-mentioned seven pesticides were dissolved in benzene and spotted on a thin plate with a 10 μl syringe at a concentration of 20 ppm. The sheets were dried in an oven and spread out in the following solvent system: benzene: cyclohexane: n-hexane: xylene: methylcyclohexane: toluene (50:50:50:50:50:50). Expand to be dried and sprayed with 1% (V / V) tolidine solution. Then hot air drying,
