摘要
本方法研究了水样中ＤＤＶＰ、地亚农、乐果、甲基对硫磷、内吸磷、马拉硫磷、水胺硫磷、乙硫磷和乙基谷硫磷等九种有机磷农药的气相色谱分析方法。该方法用三氯甲烷提取水中的有机磷农药，毛细管柱分离，程序升温，ＦＰＤ测定。方法操作简单，测定水中有机磷农药的最低检出浓度在２．８ｎｇ／Ｌ至０．０２９ｍｇ／Ｌ之间，加标回收率在７０．０％～１２０％。方法适用于地表水、地下水和废水中痕量有机磷农药的测定。
The determination of nine organic phosphorus pesticides,Dichlorovos,Diazion,Dimethoate,Parathion-methyl,Isocarbophos,Demeton,Malathion,Ethion andGluthion-ethyl,is studiedThe analytical procedures are as follows:extraction by trichloro-methlane;separation with capillary column;temperature programming and determination by FPDThe detection limit is 2.8ng/L to 0.029mg/LThe recovery rate is from 70% to 120% The method can be used to determine trace organic phosphorus pesticides in various kinds of water and wastewater
