GC-ECD定量检测榴莲、山竹中20种有机氯类、菊酯类农药残留

GC-ECD quantitative detection on 20 kinds of organochlorine and pyrethroid pesticides in durian and mangosteen

建立了一种利用气相色谱仪-电子捕获检测器检测榴莲、山竹中20种有机氯类、菊酯类农药残留的方法.榴莲和山竹都因其独特口感受到大家喜爱,消费市场巨大.但目前国内外对这两种水果中有机氯类、菊酯类农药残留的检测仍处于空白.建立快速方便、简单准确地检测出两种热带水果中20种有机氯类、菊酯类的农药残留的方法,该方法检出限在0.001～0.149 mg/kg之间,RSD值为3.2％～11.6％,添加回收率在70.66％～126.37％之间.

A method for detection on 20 kinds of organochlorine and pyrethroid pesticides in durian and mangosteen by gas chromatograph-ECD-detection （GC-ECD） was established. Durian and mangosteen are well weleome because of their unique taste. The detection of organochlorine and pyrethroid pesticides in durian and mangosteen has not been explored at home and abroad yet. The method in this article was simple, rapid, sensitive and accurate, and showed that the lowest limit was 0.001-0.149 mg/kg, and the recovery range was 70.66%-126.37% with relative standard deviation 3.2%- 11.6%.
