呋喃丹是一种广谱,高效氨基甲酸酯类杀虫剂,广泛用于粮食、水果、蔬菜等农作物中。关于空气中呋喃丹的测定方法,国内有比色法、高效液相色谱法,国内外亦有将其转比成三氟乙酰衍生物用气相色谱分析的报道,但多用于残留量的分析。本文参考有关文献,建立了空气中的呋喃丹用玻璃纤维滤纸采集,乙酸乙酯洗脱,以吡啶做触媒经三氯乙酸酐衍生后,用 Carbofuran is a broad spectrum, highly efficient carbamate insecticide that is widely used in crops such as food, fruit, vegetables and the like. Determination of carbofuran in the air, the domestic colorimetric method, high performance liquid chromatography, but also at home and abroad have also been converted to trifluoroacetyl derivatives by gas chromatography analysis of the report, but more for the residue analysis. In this paper, reference to the literature, established in the air carbofuran collected with glass fiber filter, ethyl acetate elution, with pyridine as a catalyst derived from trichloroacetic anhydride, with
