Following the Reaction of Chemical Warfare Agents on Adsorbents by Transmission Fourier Infrared Spectrometry; Conference paper

摘要

The reactions of HD, VX, and GD on metal oxides and core-shell metal oxides were followed by transmission FTIR. The decomposition was determined by the decrease in characteristic absorption peaks noted for each agent. The increase in the characteristic absorption peaks for hydrolysis products was also used to verify the reactions. Typical absorbance bands for agent and major hydrolysis product were as follows: GD (1320 cm-1) and PMPA (1189 cm-1), HD (1295 /cm and 1212 /cm) and TDG (1059 /cm), VX (1299 /cm) and EMPA (1315 /cm). Two different samples of aerogel prepared magnesium oxide (AP-MgO) demonstrated significant GD reactivity over 20 hours at room temperature. Little or no agent decomposition occurred on the other adsorbents. The work supported the Destructive Adsorption program.
