| Aim: The course gives basic knowledge on the hydrogeochemical processes controlling the composition of natural waters in terms of dissolved and solid constituents. The primary goal is to apply traditional chemical principles on geochemical systems using data obtained from different analytical techniques. Prerequisites: Approved NKEA11-13 General Chemistry 1-3, and attended NKEB21 Inorganic Chemistry 2, NKEB22 Organic Chemistry 2 and NKEB44 Analytical Chemistry, respectively. Course organization: The course consists of lectures, laboratory work, lessons, seminaries and excursions. It is given by the Department of Water and Environmental studies. Course content: The theory of geochemistry serves as model for interpreting data obtained from several analytical techniques, applied to natural waters from various environments. Theory: The cycling of water in different spatial as well as time scales is important for the composition of different constituents due to interactions with geological phases. The composition of natural waters are interpreted from hydrogeochemical principles, which are derived from traditional thermodynamic relationships between dissolved and solid constituents. Kinetically controlled systems are also included. Principal redistribution processes (precipitation, occlusion, adsorption) are exemplified in surface water, ground water and pore water systems. Laboratory work: A number of techniques for accurate sampling and analysis of mainly inorganic constituents are included in the course. Apart from serving their own purpose it is important to emphasise that the results are used to illustrate some of the theoretical principles discussed above. Quantitative trace metal analysis and empirical speciation of their dissolved and solid forms are discussed in detail. Analytical results are also used as input in geochemical modelling where some computer codes are introduced. Course literature: To be announced later. | ||
