DESCRIPTION OF THE GROUP

In 2013, we initiated the implementation of a project called “Greenmet” under Measure 1.4 of the Innovative Economy Operational Programme. As part of this project, we carry out research on the selective recovery of non-ferrous and precious metals from technological waste and electronic scrap, with innovative (in terms of technology, environment and economy) chemical and electrochemical methods (at macro, micro and nano-scale). The project has a strictly application character in the area of environmental protection. The innovativeness of the proposed solutions is expressed by their selective action on a selected metal (targeted recycling), simplicity of operation and environmental friendliness (lack of toxic by- products, ease of regeneration of key reagents). The quantitative indicators of the developed methods confirm their belonging to the area of eco-friendly technological solutions (green chemistry). In order to achieve the assumed indicators, we are also making efforts to design and synthesize new materials.

RESEARCH ACTIVITIES

New inorganic compounds and gel materials (e.g. ferro-gel materials, i.e. gel materials sensitive to changes in the external magnetic field) are de-signed and characterized for selective extraction or accumulation of selected metals. The development of fast and reliable methods for multielement chemical analyses is also an important part of the research work. Analytical procedure schemes built are subject to full validation. The process of quality control of the obtained measurement results (including validation of the method, estimation of measurement uncertainty, comparative activities) is carried out with the use of our in-house e-stat service

OFFER:

  • Electroanalytical measurements using macroelectrodes (industrial samples), microelectrodes (environmental samples) and nanoelectrodes (extremely small volume samples including intracellular measurements),
  • Fabrication of nanoelectrodes,
  • Chemical analysis of solid samples by X-ray fluorescence technique (XRF),
  • Determination of metals in solid samples with measurement capability directly at the place where the material is stored, without the sample having to be transported to the laboratory,
  • Consultations/workshops on validation of test methods and construction of budgets for uncertainties of methods,
  • Developing schemes of validation / estimating the uncertainty of analytical, physico-chemical and physical methods in research laboratories,
  • Analysis of large  data sets using chemometric techniques.
