Selective ligands for strategic elements
Extraction of strategic and critical elements from the fly ash of (waste) incineration plants
The strategic elements indium (In) and gallium (Ga) as well as the base metal tin (Sn), are of great importance for numerous industrial applications (including communication technology, photovoltaics, electromobility). However, they are also considered to be critical raw materials due to their highly limited availability. For this reason, our research project is focussing on the effective and selective recycling of these raw materials.
For recycling, solvent extraction processes are used, which are based on an acidic, aqueous solution of the corresponding metal salts. The latter are transport back into an aqueous environment with the help of suitable ligand molecules via an organic solvent phase.
