本文确立了有机磷系农药的4个组分(对硫磷甲基对硫磷苯硫磷及甲基内吸磷)的同时萃取,净化及气相色谱定量法。即用含有10％氯仿的正己烷萃取,浓缩后注入气相色谱(火焰光度鉴定器)内,同时测定4个组分,采用此法水质试样需取样200毫升,定量下限为0.001ppm或在此值以下。此外,对于土壤、生产废物、工厂污水等极污浊的试料,将其浓缩液,注入经活化的硅
In this paper, four components of organic phosphorus pesticides (parathion methyl parathion parathion and methyl phosphorus uptake) were simultaneously extracted, purified and determined by gas chromatography. That is, extracted with n-hexane containing 10% chloroform, concentrated and injected into the gas chromatograph (Flame Photometric Detector), while measuring four components, using this method, the water quality sample to be sampled 200 ml, the lower limit of quantification of 0.001ppm Value below. In addition, for soil, production waste, factory effluent and other very dirty samples, the concentrated liquid is injected into the activated silicon
