| 101-0339-00L | Environmental Geotechnics – Polluted Sites and Waste Disposal | 3 credits | 2G | M. Plötze | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | The practice of landfilling, remediation of polluted sites and the disposal of radioactive waste are based on the same concepts of environmental protection. Understanding the contaminants behaviour and how to reduce their release to the environment is the key to remediating polluted sites and designing multi-barrier systems. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | On successful completion of this course students will be able to - Assess the risk to the environment from landfills, contaminated sites and radioactive waste repositories in terms of the fate and transport of contaminants. - Describe the technologies available to minimise environmental contamination - Describe the principles of dealing with polluted sites and propose and evaluate appropriate remediation techniques - Explain the concepts underlying radioactive waste management practices. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | This lecture course consists of lectures with exercises and case studies. - An overview of the principles of environmental protection in waste management and how this is applied in legislation. - An overview of the chemistry underlying the release and transport of contaminants from the landfilled/contaminated material/radioactive waste repository focusing on processes controlling mobility of heavy metals and organic compounds - Introduction to contaminant transport in porous adsorbing media - Design and function of engineered barriers. Clay as a barrier. - Polluted site remediation: Site investigation, assessment, and remediation technologies - Concepts and safety in radioactive waste management - Role of the geological and engineered barriers and radionuclide transport in geological media. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 651-4063-00L | X-Ray Powder Diffraction  | 3 credits | 2G | M. Plötze | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | In the course the students learn to measure X-ray diffraction patterns of minerals and to evaluate these using different software for qualitative and quantitative mineral composition as well as crystallographic parameters. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | Upon successful completion of this course students are able to: - describe the principle of X-ray diffraction analysis - carry out a qualitative and quantitative mineralogical analysis independently, - critically assess the data, - communicate the results in a scientific report. The competencies of system understanding, concept development, and measurement methods are taught and examined. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | Fundamental principles of X-ray diffraction Setup and operation of X-ray diffractometers Interpretation of powder diffraction data Qualitative and quantitative phase analysis of crystalline powders (e.g. with Rietveld analysis) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lecture notes | Selected handouts will be made available in the lecture | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
