Abstract : In order to develop an effective hydrazine remediation technique, the environmental fate and transport of its breakdown products must be identified and quantified. Hydrazine and methyl hydrazine auto-oxidation were studied in the presence of colloidial hematite, a common soil mineral. It was found that auto-ozidation in the presence of the hematite was attenuated when compared to auto-ozidation in water only. This indicates that the interaction between the hydrazines and the hematite in some way protects the hydrazines. The specific interaction between the hydrazines and hematite was investigated using fourier transform infrared spectroscopy using attenuated total reflectance sampling (FTIR-ATR) enabling direct spectral analysis of the interaction without the interference of chemical diluents such as potassium bromide, which are used in more common FTIR methods. These analyses indicated that the interaction is probably due to electrostatic interactions, including hydrogen bonding between the hydrazines and the oxygens, or the first hydration spheres, on the hematite. It was found that the interaction changes with time, and that the interaction is stable to heating, and appear to have a long lifetime, indicating a strong final interaction. Similar results were found when the FTIR-ATR was also used to analyze the interaction of the hydrazines with common clay minerals.
