Contents:

Various aspects of chemical interactions of compounds in the soil-water environment (nutrients, contaminants) and their applications are part of this course. Most relevant processes are speciation (especially adsorption and complexation) and mass transport. Applications focus on practical calculation and measurement methods.
Lectures: fundamental aspects and practical applicability of speciation and mass transport in soil, groundwater and surface water; applications to soil remediation and water purification, soil fertility, water quality, risk assessment, etc.
PC practical: structural approach in solving chemical equilibria (speciation calculations) using a computer model (ECOSAT).
Lab practical: determination of adsorption behaviour of heavy metals to solid and suspended particles (clay, oxides, organic matter); chemical analysis (AAS, TOC, pH); parameter fitting (multiple linear regression). Tutorials: assignments related to lecture topics, explanation and exercises supporting lab-practical and pc-practical; simulation of adsorption behaviour using a speciation model (ECOSAT).

Learning outcomes:

- conduct laboratory experiments to determine adsorption isotherms, analyse important chemical soil and water characteristics and interpret experimental results;
- analyse speciation problems in soil-water systems and perform speciation calculations with a computer speciation model;
- describe and predict compound behaviour in soil and surface water;
- describe applicability of speciation and mass transport in soil and water chemistry.

Activities:

- attend lectures and tutorials; hand in assignments;
- conduct laboratory experiments; write practical report;
- do PC practical on speciation calculations.

Examination:

Hand in assignments (2 per week; 6 total) and practical report; complete pc practical.
Contribution to final mark: average of all assignments 50%, practical report 25%, PC-practical 25%.
Each part should get a minimal score of 5.5 (scale 0-10).
