The department carries out researches of decontamination processes of hazardous chemical waste (mainly aqueous solutions) using modern methods and equipment in order to utilize or regenerate valuable chemical substances. For many years, the research-based technologies are used successfully in economic – commercial activities of the FTMC decontamination of hazardous chemical waste bar, providing services to the country‘s industrial plants.
For many years, researches of water and industrial wastewater treatment processes are carried out successfully using the following sorbents: modified activated carbons, zero-valent irons, nano-sorbents, synthetic and natural (chitosan) sorbents and iron oxides/hydroxides nanoparticles prepared using iron wastes from drinking water treatment plants.
An important scientific research trend is a development of environmentally friendly technological processes. It includes a development of plastic chrome - free metallization technologies applying different than usual methods of plastic activation and etching against chemical metallization. The results of these researches were successfully commercialized in Germany and the USA.
The department has a laboratory of chemical coatings that provides services for economic entities, forming coatings with aluminium anodic layer with special properties.

Laboratory


Equipment

The department uses an equipment to analyse ions and volatile organic substances in aqueous solutions. It is a capillary electrophoresis equipment “P/ACETM MDQ Capillary Electrophoresis System” and gas chromatograph with mass detector Shimadzu GCMS – QP2010.
Applied works are carried out using vacuum water evaporation system WT55 HPR and ozone generator SF 85.
