Surface Analysis of Environmental Systems
Surface Raman and Infrared Spectroscopy to Probe
Organic Pollution of Soil Samples
A problem of considerable importance today is the presence of organic pollutants in the soil and groundwater. An understanding of the mechanisms by which organic contaminants adsorb to mineral surfaces will be critical in predicting their fate and transport in the environment. This research project seeks to identify the mechanisms which control the sorption and degradation of organic pollutant compounds at soil and mineral surfaces. Raman and infrared spectroscopy are used because these techniques provide the molecularly specific information necessary to study pollutant-mineral surface interactions. This research will provide a fundamental understanding of sorption processes at contaminated sites, such that proper remediation strategies can be implemented.
Characterization of Atmospherically Relevant Surface Reactions
Raman, AFM, and X-ray Photoelectron Spectroscopy of Surface Reactions
The fate and transport of species in the atmosphere has gained heightened attention since the discovery of the ozone hole and the recognition that ice surfaces play in its creation. Reactive chlorinated species in the atmosphere are responsible for the destruction of ozone; thus the source, fate, and transport of these species are actively being studied. Research focused on two areas of fundamental importance in the addition of chlorinated species to the atmosphere, and the fate of many such species are being pursued.
