If you have a question about this talk, please contact Catherine Pearson .

Reactions at the solid-fluid interface control a range of low-temperature geochemical processes, including contaminant adsorption, nutrient release, dissolution, and precipitation. Understanding the details of mineral and glass surface chemistry during reaction is complicated by the presence of the aqueous fluid and by the low number of atoms present in the reactive surface volume. Several surface sensitive spectroscopic techniques have been developed (e.g. X-ray reflectivity, polarization dependent EXAFS , MIR-FTIR) in order to study such systems during reaction. Here, recent work with x-ray and infra-red spectroscopic methods will be presented, covering several natural and applied case studies with a range of substrates and solutes.
