Abstract

Since all reactions are driven by net energy flow, the direct measurement and analysis of binding and debinding energetics should provide valuable data and insights into the dynamics of organic molecules at the oxide-water interface. The study will report on binding-debinding energetics of selected low molecular weight organic acids, amino and poly-amino acid on the surfaces of silicon oxides of the form SiO2. The study will focus on the systematic collection and analysis of experimental data that can be used to support the development, validation and refinement of computational models of interactions involving natural organic matter at the metal oxide-water interface, while facilitating the further development of experiment-driven understanding of binding-debinding dynamics of organic molecules onto mineral surfaces.
