Course Description

Industry Related Element Speciation


Ecotechnologies, second-level study programme


prof. dr. Radmila Milačič
prof. dr. Janez Ščančar


To introduce the students the importance of speciation analysis in different industrial branches.
Students will gain basic knowledge on different industrial processes where chemical speciation plays a crucial role. Transformation of chemical species of elements in different industrial processes will be presented. Problems related to industrial wastes and safe wastes disposal will be also presented.
The potential of the re-use of different waste materials as secondary materials that can substitute natural materials will be evaluated. The role of speciation in these activities will also be assessed.
The solutions of the environmental problems related to specific industrial activities will be proposed.


• The overview of industrial processes where speciation plays a crucial role (Arsenic in glass production, the role of speciation in mining and the solution of environmental problems as a consequence of mining activities, air pollution as a consequence of fossil fuels (e.g. arsenic in aerosols), the role of chromium speciation in industry and civil engineering (speciation of chromium in leather industry, sewage sludge, speciation of chromium at workplace of welders, speciation of chromium in car industry), speciation of mercury in chemical industry (oil industry, thermal power plants, pharmaceutical industry….), fractionation of mercury in construction materials.
• The solution of technological and environmental problems related to legislative demands (The role of speciation of arsenic in clean-up of waste waters from glass production, safe disposal of waste materials from industrial processes (e.g. chromium in tannery waste, safe disposal of sewage sludge).
• Re-use of waste materials and environmental impacts (e.g. the potential of re-use of waste materials from steel production in civil engineering and road construction and the assessment of environmental impact regarding the content of hexavalent chromium).
