The work shortly describes scientific, teaching, and organisational activity of the Chair of Chemistry and then of the Division of Physical Chemistry during after-war period. Presentation is made in five short chapters, covering periods defined by substantial and characteristic processes in our country, resulting in changes in the organisation and work of the Faculty of Chemistry at the University of Warsaw. The first two chapters concern the Chair of Physical Chemistry at the Faculty of Mathematical and Natural Science in the years 1947–1955. The Department of Chemistry was founded in the 1955. The next three chapters describe the activity of the Division of Physical Chemistry in the years 1968–1989, 1990–2005, and 2005–2016 respectively. The work also contains a register, probably incomplete, of employees with university degree, who were employed at the Chair and then at the Division of Physical Chemistry during 61-year period of the activity of the Faculty, i.e. in the years 1955-2016.

For decades electrochemical technology has contributed successfully to environmental protection. Electroanalytical techniques have been frequently used in monitoring the changes of environment. In industry, electrochemical technologies can provide higher purity in technological processes and they can also limit a degradation of the environment in comparison to the common chemical methods. Electrochemistry has been also very useful in developing and in the production of new energy sources. A lot of attention has been paid to studies of environmentally friendly hydrogen fuel cells. The electrochemical techniques of waste degradation can be divided into two main categories: (i) techniques based on the faradaic processes of oxidation or reduction of contamination, and (ii) electrokinetic methods based on the transport of ions or charged particles in the electric field. The electrode processes result in the formation of deposits on the electrode surface or the decomposition of large organic molecules to the low molecular weight, easily biodegradable molecules or CO2. The electrokinetic techniques include electrocoagulation, electroosmosis, electrodialysis, and electroflotation. These techniques are widely used in removing contaminants from soil. This paper is focused on selected topics related to the environmentally friendly application of electrochemistry.
