About the Course

Aqueous Geochemistry

  • Monday 27 November - Friday 1 December 2017

Find out how to use techniques for evaluating geochemical reactions. Use computer-based models to solve a variety of problems.

This course introduces some of the techniques used to quantify geochemical reactions between dissolved species and mineral phases.

You'll be introduced to the quantitative, equilibrium-based methods used to understand the controls on the chemical composition of both surface and groundwaters.

You'll learn how we can use:

  • simple thermodynamic principles to quantify the potential for reactions between dissolved solutes and solid phases
  • computer-based models to solve a range of geochemical problems and water quality issues, such as mine water pollution.

Who is the course aimed at?

The course is aimed at environmental geochemists, environmental engineers, geologists, biologists interested in understanding the factors which control the chemical composition of natural waters and geochemical processes that occur in aquatic, terrestrial and subsurface environments.

Objectives and Outline

Aqueous Geochemistry

Course Objectives

By the time you've finished this course, you'll understand:

  • the usefulness and limitations of equilibrium as a way of describing and quantifying water-rock reactions;
  • how simple thermodynamic principles can be used to quantify the potential for reactions between dissolved solutes and solid phases;
  • how computer-based models are used to solve geochemical problems;
  • the importance of acid-base and oxidation-reduction reactions in natural environments;
  • the difficulty of quantifying redox potential.

You'll also:

  • know the difference between measured concentrations of dissolved elements and their chemical activity;
  • be aware that most elements exist in solution as both as single ions and as ion complexes and will realise why this is important in the quantification of geochemical reactions in aqueous systems.
  • be capable of using simple equilibrium thermodynamic calculations to describe natural aqueous systems;
  • have some experience of geochemical modelling using Geochemists Workbench.

Course Outline

  • Equilibrium, disequilibrium and the Law of Mass Action;
  • Activity and activity coefficients;
  • Acids, bases and alkalinity;
  • Practical equilibrium thermodynamics;
  • Redox geochemistry; Eh-pH diagrams;
  • Computer-based geochemical modelling: practice and pitfalls.
