FAE3010 Environmental Geochemistry and Ecotechnology 7.5 credits

Miljögeokemi och ekoteknik

After the course, the PhD student should be able to:

provide an overview of current research topics and to discuss recent findings in the area of environmental geochemistry and ecotechnology know the principles of important methods for material characterization, including X­ray powder diffraction and X­ray absorption spectroscopy interpret and statistically treat water chemistry data (spatially or temporally distributed) in a scientifically sound way, using spreadsheets or geochemical software

discuss how to design projects that address important research issues with state­of the art analytical techniques and results interpretation.

Main content

The course includes a seminar programme. Eight seminars of which at least six must be attended to pass the course. Topics of the ten seminars:

Current research trends in Environmental Geochemistry and Ecotechnology

Binding of metals and nutrients in soil and ground. Mechanisms and environmental relevance The arsenic problem in groundwater ­ an overview

Use of ecotechnology for passive treatment of sewage and contaminated water Evaluating mineral phase composition by means of X­ray powder diffraction Use of X­ray absorption spectroscopy to unravel speciation and structures Geochemical modellin; overview of sftware and tools to intepret chemical data Guest lecture on selected topic

Between each seminar, participants should discuss defined aspects of each talk. Each seminar ends with discussion of the previous seminar. Exercises:

X­ray powder diffraction ­ data acquisition and interpretation

X­ray absorption spectroscopy ­ introduction to interpretation of EXAFS and XANES data Speciation modelling with Visual MINTEQ

In addition, a project work assignment is included in which course participants tackle data from own research with methodology related to the course.

Content and learning outcomes

Course contents *

The course includes a seminar programme. Eight seminars of which at least six must be attended to pass the course. Topics of the seminars:

- Current research rends in Environmental Chemistry and Ecotechnology.

- Binding of metals and nutrients in soil and ground. Mechanisms and environmental relevance.

- The arsenic problem in groundwaters - an overview.

- Use of ecotechnology for passive treatment of sewage and contaminated waters.

- Evaluating mineral phase composition by means of X-ray powder diffraction.

- Use of X-ray absorption spectroscopy to unravel speciation and structures.

- Geochemical modelling; overview of software and tools to interpret chemical data.

- Guest lecture on selected topic.

Between each seminar, participants should discuss defined aspects of each talk. Each seminar ends with discussion of the previous seminar.

Exercises:

- X-ray powder diffraction - data acquisition and interpretation.

- X-ray absorption spectroscopy - introduction to interpretation of EXAFS and XANES data.

- Speciation modelling with Visual MINTEQ.

In addition, a project work assignment is included in which course participants tackle data from own research with methodology related to the course.
