Abstract:In order to understand the current status of organophosphorus pesticide residues in vegetables in the city's agricultural products market，to develop relevant countermeasures,a rapid detection method for a variety of organophosphorus pesticides was established.According to the characters of pesticides，the gas chromatography could simultaneously detect 15 organophosphorus pesticides，including：trichlorphon，dichlorvos and methamidophos，acephate，destroy the line p，phorate，oxygen dimethoate，butyl sulfur,phosphorus,dimethoate，methyl parathion,marla s p，fenitrothion，parathion，fenthion，isocarbophos.Through the selection of different types of chromatographic column and the control of temperature rise program of column temperature box，the rapid，convenient and accurate qualitative and quantitative analysis of 15 kinds of common organophosphorus pesticides is realized.The main purpose was to find a method that could detect a variety of organophosphorus pesticides at the same time,and try to find a way to detect a variety of organophosphorus pesticides at the same time with the shortest time，the least consumption of raw materials and the best detection effect.
