摘要: Abstract A method is described for the isolation of decomposition products nerve agents from aqueous solutions and their determination by gas chromatography. The methylphosphonic acids were retained on an aminopropyl ion exchanger eluted with trimethylphenylammonium hydroxide, which also acted as a methylating reagent. procedure was applied to environmental samples in field exercise contaminated sarin soman exposed prevailing weather periods up 4 weeks. detected all examined.
