303 Approaches for Measuring Kinetic and Thermodynamic Properties of Processes at the Mineral/Water Interface

Chemical reactions at the solid/water interface play a fundamental role in the processes governing the behavior of nutrients and pollutants in soil environments. Comparably fewer studies are aimed at measurement of kinetic and thermodynamic data. These data can be obtained through a variety of established and emerging techniques such as synchrotron spectroscopies, fast acquisition FTIR, and flow and titration calorimetry. This session will highlight research on current as well as “in-development” approaches for measurements of kinetic and thermodynamic data within the aqueous-mineral interface. We encourage submissions showcasing results using any number of experimental approaches as well as theoretical studies.
