WebFOCUS Report
Project description
This research project aimed to find new chelating ligands for the selective extraction of metals, particularly uranium (as the uranyl dication), from different (aqueous) solutions. The research was carried out at the University of Jyväskylä and it involved mostly computational methods. Ligand systems that were deemed to be most promising based on computational simulations were also manufactured synthetically. The research project succeeded in building a new filter system for the extraction of important metals, mostly uranium, scandium and iron, from synthetic mining raffinates. The filters were manufactured using 3D-printing techniques and selective laser sintering in particular. Filters that would have been fully selective to uranium could not, however, be realized.
