- Teaching methods
The preliminary knowledge of the basis of General and Inorganic Chemistry, as well as Organic Chemistry, is required.
The exam will consist in 4 questions, in written form, in order to evaluate final preparation of the student on all topics presented during the course. Each question will have a score of 7.5 point. The score will be in thirtieth (/30), for a final score of 30/30.
The Environmental Analytical Chemistry course will provide the student an integrated approach to the principles and evaluation of modern analytical chemical methods. This approach will be focussed on all environmental, as well as natural, compartments.
At the end of the course, the student will become familiar with :
- the theoretical and practical aspects of the modern instrumental analysis in the environmental field, as well as the statistical approach to data analysis.
- the choice and the application of such methods to sampling and analysis of solid and liquid samples.
- the critical evaluation of the obtained analytical data, as well as its statistical treatments, towards a multidisciplinary approach, paricularly for toxicological and mineralogical aspects.
The student will learn the theoretical basis and the applications of modern instrumental analytical techniques.
Particular emphasis will be given to in-situ techniques and their application to environmental analysis.
