Molecular-Based Studies of Geochemical Interfaces in Complex Environments
Abstract
Major Goals: The major goals of the project include: Goal 1: to understand the transformation of chemical contaminants, such as industrial solvents and personal care products, on geochemical interfaces. These contaminants include monoethanolamine, 2-butoxyethanol and methyl ethyl ketone and represent a broad class of compounds that include amino alcohols, glycol ethers and ketones, respectively. Goal 2: to probe and understand the behavior of biological components, oxyanions, and dissolved organic matter on geochemical interfaces in complex media. The purpose of this goal is to both interrogate the surface of geochemical interfaces with different biological components and to also go beyond one at a time component interactions that most studies investigate in order to build towards a more relevant, multi-component system bound in the environment. This will allow for us to begin to unravel the chemical complexity of competing surface species and the possible synergistic effects of multi-component systems. Goal 3: to develop new micro-spectroscopic tools to investigate the chemistry occurring on geochemical interfaces. This goal is focused on investigating geochemical interfaces using spatially resolved molecular-based spectroscopic probes. This novel approach will be particularly useful in discerning the complex nature of adsorbate-surface interactions at geochemical interfaces in multi-component environments.
