N,N-dichloro poly(styrene-co-divinyl benzene) sulfonamide polymeric beads: An efficient and recyclable decontaminating reagent for O,S-diethyl methyl phosphonothiolate, a simulant of VX

Authors


Abstract

An efficient and operationally simple method is developed for chemical decontamination of simulant of VX. A new chlorine bearing reagent N,N-dichloro poly(styrene-co-divinyl benzene) sulfonamide was developed to deactivate the simulant of VX in aqueous medium. This decontamination reaction was monitored by gas chromatography (GC), and the products were analyzed by gas chromatography-mass spectrometry (GC-MS). This reagent has advantage over earlier reported reagents in terms of effectiveness, stability, nontoxicity, cost, ease of synthesis, recyclablity (collected after filtration, rechlorinated, and used for further reaction), and decontamination of simulant of VX to give single nontoxic product at room temperature. © 2011 Wiley Periodicals, Inc.
