Synchrotron X-ray scattering studies at mineral-water interfaces

PDF Version Also Available for Download.

Description

Synchrotron X-ray scattering techniques provide a powerful tool for the in situ study of atomic scale processes occurring at solid-liquid interfaces. We have applied these techniques to characterize and study reactions at mineral-water interfaces. Here we present two examples. The first is the characterization of the calcite (CaCO{sub 3}) (10{bar 1}4) cleavage surface, in equilibrium with deionized water, by crystal truncation rod measurements. The second is the in situ study of the heteroepitaxial growth of otavite (CdCO{sub 3}) on the calcite (10{bar 1}4) cleavage surface. The results of such studies will lead to significant progress in understanding mineral-water interface geochemistry.
