Degradation of Mustard on Concrete: GC/MSD and SSMAS
Abstract
The products formed from the degradation of mustard [bis(2-chlorethyl) sulfide] on concrete were identified using gas chromatography with mass spectrometry detection (GC/MSD), 13C solid state magic angle spinning (SSMAS) NMR, 1-D 1H NMR, and 2-D 1H-13C NMR. In situ and extraction experiments were performed. Mustard was detected in the in situ SSMAS samples after a period of 12 weeks, whereas less than 5% of the mustard was detected in extracts from the concrete monoliths after 8 days. Sulfonium ions and (2-chloroethylthio) ethyl ether (T) were observed on the in-situ samples after a period of 12 weeks, whereas vinyl species and bis(2-chlorethyl) sulfoxide were observed in the extracts of the concrete monoliths within 24 hr. The sulfonium ion products formed by mustard on concrete had been previously observed in aqueous solution and wet soil. The vinyl products had been previously observed on metal oxides. Sulfoxide products had been identified in reactions with bleach, but T had not been observed in any of the prior systems.
