| 摘 要： | 建立气相色谱-质谱法测定食品基质中四聚乙醛残留量。采用二氯甲烷-丙酮混合溶剂提取，石墨化炭黑/氨基复合固相萃取柱净化，气相色谱-质谱法检测大米、大豆、菠菜、番茄、洋葱、茶叶、苹果、板栗等多种植物源食品基质中四聚乙醛残留的方法。结果表明，该方法定量限为0.01mg/kg，在添加0.01～0.5mg/kg范围内，加标回收率为70.5%～111.7%，相对标准偏差为4.4%～11%。

| Abstract: | A gas chromatography-mass spectrometry(GC-MS) method was developed for determining metaldehyde residue in various food matrixes including rice,soybean,spinach,tomato,onion,tea,apple and Chinese chestnut.Metaldehyde residue in samples was extracted with acetone-methylene mixture,and then the extracts were purified with LC-NH2/Envi-carb solid phase extraction(SPE) cartridge.The limit of quantification(LOD) of the developed method was 0.01 mg/kg,and the average recoveries and relative standard deviation(RSD) f... |
