SMILE is a project dealing with reactive transport.

The main goals of SMILE is

  • the extension of the concept developed up till now towards inclusion of redox-reaction,
  • to corroborate the chemical description of interfacial reactions via more fundamental insight in structure, stoichiometry and thermodynamic parameters of relevant surface complexes,
  • to compare state of the art surface complexation in the evaluation of available experimental data,
  • to extend the experimental data basis via batch- and column experiments on laboratory systems,
  • to calculate smart Kd-martrices for selected redox-systems, and
  • to apply the concept and verify the concept via experiment and modeling for systems that are closer to environmental systems in a critical manner.

This is supposed to pave a fundamental basis allowing to transfer the smart-Kd-concept to various geological settings. Additionally this will allow for the coupling of the concept to geochemical reactive transport codes to be initiated.
