Geochemical processes, mineral-water interface

Effects on Geochemical Processes at the Mineral-Water Interface... 

Many IMPORTANT GEOCHEMICAL PROCESSES occur at mineral-water interfaces. Iron and aluminum are mobilized in soils by the dissolution of oxide md silicate minerals or of amorphous oxide coatings on soil minerals (I, 2). The leaching of iron and aluminum immediately below the organic-rich layers... 

Paul Fenter attended the Rensselaer Polytechnic Institute from 1980-1984 where he received a B.S. in Physics, and attended the University of Pennsylvania from 1984-1990 graduating with a PhD. in Physics. From 1990-1997 he was a postdoctoral fellow and then a research staff member at Princeton University. He joined the staff at Argonne National Laboratory in 1997 where he uses synchrotron X-ray scattering techniques to probe geochemical processes at mineral-water interfaces.

Solutions are of utmost importance in the environment Figure 7.2). Solutions transport environmental chemical species in the aquatic environment and are crucial participants in geochemical processes. Dissolution in rainwater is the most common process by which atmospheric pollutants are removed from air. Acid rain is a solution of strong mineral acids in water. Many important environmental chemical processes occur in solution and at the interface of solutions with solids and gases.
