嘧啶氧磷、地亚农、甲基1605、杀螟松、敌百虫是我国目前广泛使用或建议投产的农药品种。测定它们在农产品中的残留量,是决定它们的投产和应用迫切需要解决的问题。目前国内外报导的有机磷农药残留量的分析方法,多数采用柱层析纯化或液——液分配法进行样品抽提液的纯化。本文报导样品抽提液不经纯化处理直接进行气相色谱FPD测定的快速法(下称快速法)。它具有准确度高、快速、简便等特点。
Pyrimidine, Diya Nong, methyl 1605, fenitrothion, trichlorfon is widely used in our country or the proposed production of pesticides. Determination of their residues in agricultural products, is to determine their production and application of urgent problems to be solved. At present, the analysis methods of organophosphorus pesticide residues reported at home and abroad mostly use column chromatography purification or liquid-liquid partition method to purify the sample extract. This article reports the sample extract without purification directly by gas chromatography FPD fast method (hereinafter referred to as fast method). It has high accuracy, fast, simple and so on.
