| 摘 要： | 建立同时测定火锅底料中17 种有机磷农药残留的气相色谱法。样品经凝胶渗透色谱、固相萃取小柱净化，DB-1701 毛细管气相色谱柱分离，采用火焰光度检测器检测。火锅底料中17 种有机磷农药的加标回收率为81.83%～105.4%，RSD 为0.9%～5.2%，检出限(LOD)为1.0～5.3μg/kg。该方法具有快速、准确、检出限低等特点，能满足火锅底料中多种有机磷农药残留检测的需要。

| Abstract: | A multi-residue analytical method for the determination of 17 organophosphorus pesticides in hotpot condiment using gas chromatography equipped with a DB 1701 capillary column and a flame phosphorous detector (FPD) was developed. Gel permeation chromatography (GPC) and solid phase extraction were used to remove fats and pigments in hotpot condiment. The spiked recoveries ranged from 81.83% to 105.4% with a relative standard derivation (RSD) varying from 0.9% to 5.2%, and the detection limits varied from 1.0μg/kg to 5.3μg/kg. In conclusion, the developed method is rapid, accurate and sensitive can meet the requirements for the multi-residue analysis of organophosphorus in hotpot condiment. |
