The room temperature decompositions of the nerve agent simulant diisopropyl fluorophosphate (DFP) sorbed on γ-alumina, polydivinylbenzene (impregnated with NaOH, polyethylene glycol and polyethylenimine) (DVB/NaOH), and Ambergard® XE-555, were studied in situ using 31 P MAS NMR. Hydrolysis of the P–F bond of DFP was observed on all three sorbents, which effectively detoxifies nerve agents. On XE-555, the competing process of micropore adsorption of DFP into the carbonaceous component of this sorbent was also observed. |
