Abstract

We are investigating the interaction of dimethyl methylphosphonate and diisopropyl methylphosphonate, both simulants of chemical warfare agent, on anhydrous and natural kaolinite and compare the results with those of these two simulants on titania. Infrared spectroscopy indicates the presence of multiple rotational isomers that have different interactions with the surface. Initially, we observe physisorbed species which desorb again over time. However, at later times we observe a chemisorbed species which appears stable.
