Abstract
A gas-chromatographic procedure for the determination of O-isobutyl S-2-(N,N-diethylamino)ethyl methylphosphonothioate (VX), sarin, and soman in water at levels of 2 × 10–6, 5 × 10–5, and 2 × 10–6 mg/L, respectively, was proposed. The procedure includes liquid–liquid extraction with the use of salting-out agents, back extraction, and evaporation. In this case, the VX compound was converted into O-isobutyl O-methyl methylphosphonate (a substance convenient for chromatographic determination) by the reaction with hydrochloric acid, methanol, thriethylamine, and silver nitrate.
