我国新近发展的敌百虫甲基对硫磷混合粉剂(简称敌甲粉)是取代六六六制剂的品种之一。一般分析法不能同时测定两种有效成分。单独测定甲基对硫磷制剂的高效液相色谱法早有报导。Szalontai用液固吸附色谱法、氢火焰检测器,分析了敌百虫等23种有机磷农药标准物。迄今未见高效液相色谱法同时测定二者的文献。我们研究的高效液相色谱法可同时直接测定敌甲粉两种有效成分。二者分解产物不干扰分析。方法简便快速,定量结果准确。
China’s recent development of trichlorfon methyl parathion mixed powder (referred to as the enemy armor powder) is one of the varieties to replace the six six six preparations. General analysis can not simultaneously determine the two active ingredients. High performance liquid chromatography (HPLC) for the determination of methyl parathion alone has long been reported. Szalontai liquid-solid adsorption chromatography, hydrogen flame detector, analysis of trichlorfon and other 23 kinds of organophosphorus pesticide standards. So far no high-performance liquid chromatography simultaneous determination of both literature. We studied the high performance liquid chromatography can be directly measured Erymeria two active ingredients. The two decomposition products do not interfere with the analysis. The method is simple and fast with accurate quantitative results.
