硫代有机磷农药经中性次氯酸钠氧化后,用火焰光度检测器作气相色谱分析。作者以桃、苹果、莴苣和越桔等四种样品作为基质,在其中分别加入二嗪农、马拉硫磷、对硫磷、甲基对硫磷、杀螟松、皮蝇磷等六种农药,使各别的含量达0.25～0.5 ppm。试验证明,这些农药无论单独或混合存在,均可确检,操作也比较简单。 Thio-organophosphorus pesticides were neutralized with sodium hypochlorite and analyzed by gas chromatography using a flame photometric detector. The authors used peach, apple, lettuce and bilberry as samples, and added diazinon, malathion, parathion, methyl parathion, fenitrothion, Pesticides, so that the respective content of 0.25 ~ 0.5 ppm. Test proved that these pesticides, either alone or in combination, can be checked, the operation is relatively simple.
