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。
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.
