Information

Aims, contents and method of the course

The course will introduce the students into concepts and definitions of environmental colloid chemistry: the role of particle size, the formation of colloids, the different natural colloidal entities as well as the behavior and fate of natural nanoparticles and colloids in the aquatic environment and their analysis in clean and complex environmental samples. Their role in the transport of pollutants and the prerequisites for becoming a relevant pollutant vector will be explained.
General processes such as interaction, precipitation, dissolution, aggregation and depostion will be explained and ways of quantification demonstrated. Additionally typical incidental and manufactured nanoparticles will be described and their similarity with and differences to natural nanoparticles will be discussed.
Standard analytical techniques for the quantification and characterization of natural and manufactured nanoparticles will be shown and demonstrated in the laboratory. Theses are: Field Flow Fractionation, static and dynamic light scattering and single-particle ICPMS. A few practical exercises will be conducted.

Assessment and permitted materials

There will be 3 partial examinations:
34% written exam, 45 min. on 09. January 2024; 33% presentation of a scientific paper or report.
33% on exercises/lab reports to be handed in until 31.01.2023

The grading scheme is as follows:

> 87% (1); 75-86 % (2); 63-74 % (3); 50-62 % (4); < 50 % (5)35%

Minimum requirements and assessment criteria

Students attending the course successfully are able to describe the fundamental differences of dissolved and particulate compounds in the aquatic environment. They are aware of the different definitions of natural and technical colloids as well as nanoparticles and typical representatives. They can describe processes important for colloids and nanoparticles in the environment as aggregation, deposition, transformation and dissolution. They are familiar with concepts of electrophoretic mobility, zeta-potential, particle size ranges and shape factors and how they influence important processes of colloid stabilization, transport and scavenging. They can recall principles of key instrumental techniques for colloid analysis, namely Field Flow Fractionation, light scattering techniques and single-particle ICP-MS. They know the important representatives of engineered nanoparticles and can apply their knowledge from natural particles to assess their possible reactions in the environment (agglomeration, transformation, dissolution).

The written exam will reflect on course content (lectures & exercises).
The presentation evaluation is done according to
1) preparation of the topic (20%)
2) use of additional sources and information, also coupling to course content (20%)
3) quality of presentation (40%)
4) Q&A part of the presentation (20%)
