Abstract : The primary objectives of this work have been to: (1) characterize the chemistry of chemical warfare agents (CWAs) on metal, oxide, and polymeric surfaces, (2) make the first direct comparisons of the surface chemistry of CWA simulants and the agents themselves, including GB, VX, and HD, and (3) explore the chemistry of surface decontamination strategies including exposure to vaporous H2O2 and ClO2. These goals have been addressed through a concerted research effort along two fronts: CWA simulant studies at Virginia Tech and a new comprehensive effort that provides unique capabilities at the Edgewood Chemical Biological Center (ECBC) for studying the surface chemistry of CWAs. Specifically, a new state-of-the-art surface science instrument was developed at ECBC, which is the first of its kind to couple precision CWA dosing capabilities with mass spectrometry, infrared surface spectroscopy, photoelectron spectroscopy, and temperature programmed desorption methods. These techniques are providing time-resolved studies of CWA surface chemistry on important materials including those found in buildings or vehicles, within sensitive equipment, and on new coatings designed for soldier protection.
