| Abstract: | A method for the determination of seven chemical warfare agents, sarin, soman, tabun, cyclohexyl methylphosphonofluoridate(GF), O _ ethyl S _ [2 _ (dii sopropylamino)ethyl]methylphosphonothioate(VX), O _ isobutyl S _[2 _ (diethylamino)ethyl]methylphosphonothioate(RVX), mustard gas, in polluted water and grain is reported by GC and GC-MS-SIM(selected ion monitoring). The chemical warfare agents in polluted water were extracted with dichloromethane, and the extract was concentrated to 1 mL with gentle stream of nitrogen, meanwhile the agents in polluted grain were extracted with distilled water, and the extract was centrifuged, the upper liquor passed a C18 solid _ phase column, and then agents were eluted with acetonitrile. The method is simple and convenient for the treatment of sample, and suitable for trace analysis of chemical warfare agents in drinking water and grain for the army. |
