【摘要】 研究了蔬菜中甲胺磷残留分别经乙酸乙酯、氯仿萃取后 ,用气相色谱—火焰光度检测器直接测定的方法。色谱柱采用DB -WAX大口径石英毛细管柱。甲胺磷残留得到很好分离。方法给出较好的精密度和回收率更多还原

【Abstract】 A direct analytical method for methamidophos residues in vegetables,after extracting vegetable separately with ethyl acetate or chloroform, has been studied by Gas Chromatography-Flame Photometric Detection.The column used was a megabore DB-WAX capillary column.Pesticide methamidophos can be well separateed. The analytical method for methamidophos residue gives better precision and recovery.更多还原
