Cursusdoelen

At the end of the course, the students have the theoretical foundation and practical skills to interpret and predict the composition of natural or contaminated waters based on equilibrium thermodynamics. They have an overview about quantitative concepts to describe acid base properties of solids and solutions, redox speciation of inorganic and organic compounds in aqueous solution, solubility of solids, metal speciation in aqueous solution, distribution of compounds between different phases, and the adsorption of ions and organic compounds at the solid-liquid interface. The students know how to use computer-based chemical speciation models.

Inhoud

The course deals with processes that control the composition of water in aquifers, soils, lakes, and in the ocean. The focus lies on using equilibrium approaches to describe and quantify these processes. The aquatic chemistry of inorganic compounds and the behavior of organic compounds in aquatic environments are both treated in the course.

 

The course is organized around three main themes:

 

1. Speciation of dissolved compounds in aqueous solution:

Acid-base reactions, complexation of metals, redox speciation, introduction into quantitative methods in aquatic chemistry including the tableau method and speciation models.

 

2. Partitioning of compounds between different phases

Thermodynamics of equilibrium partitioning, gas – water partitioning, solid-water partitioning, liquid – liquid partitioning

 

3. Adsorption at the solid-water interfaces

adsorption isotherms, surface reactivity of solids, surface complexation, ion exchange

 

The course includes project-based work. These projects are devoted to processes controlling the composition of waters in surface and subsurface environments or the phase distribution and transformation organic compounds in aquatic environments. Computer equilibrium models will be used to solve quantitative problems related to the different projects.
