| CONTENTS: | This course seamlessly builds on Aqueous Environmental Geochemistry and deals with geochemically more complex systems and case studies. Knowledge of the form and reactivity of chemical species dissolved in aqueous solutions is a prerequisite to understanding almost all processes of rock–water interaction. This course covers a more in-depth treatment of: ion-exchange, sorption and surface complexation; redox-dependence of speciation and solubility; species-predominance and activity-activity ratio stability diagrams; kinetics of mineral dissolution and precipitation (transition state theory). PHREEQC is used as part of teaching and for solving exercises and case studies. The focus is on inorganic geochemistry, including environmentally relevant components (e.g., carbon system, sulphur system, nitrogen system, and heavy metals). Students will understand natural and man-influenced processes of rock-water interaction at the subsurface, based on theory, and learn a “geochemical and quantitative way of thinking” about how a part of nature functions. |
