For these studies, experimental methods involving microscopic (AFM, SEM), spectroscopic (TRLFS, XRD, CTR/RAXR, EXAFS) and analytic (ICP-MS, ICP-OES, IC) techniques are used. A rather unexpected but strong (negative) influence of NaNO3 on the calcite surface and respective sorption and incorporation reactions could already be shown.
These investigations aim at molecular processes in realistic systems in order to improve the understanding of geochemical surface processes.
