Learning outcomes
|
Acquaintance of students with the physico-chemical background of electrical phenomena and related processes, with an emphasis on analytical use in measurements without the passage of current and with the passage of current. One of the main aims of this subject is to highlight modern trends, such as environmental-, food-, and pharmaceutical analysis with environmentally friendly ("green") detection systems and advanced biosensors.
Graduates of the course will gain an overview on modern methods of electroanalytical chemistry, including information on the latest research results of the electroanalytical group from the Deprtment of Analytical Chemistry as a part of specialized teaching or when working on grant projects. (i) written test - 30% of the exam (ii) oral part of the exam - 70%
