Germanium, gallium, and indium are valuable elements due to their great economic importance and growing utilization in high-tech and green-tech applications. The exploitation of secondary resources, for example, tailings, slags, or end-of-life products, as well as the application of sustainable biotechnological methods, results in the challenge of separating Fe(III) from In(III), Ge(IV), or Ga(III). With common methods, such as precipitation, the selectivity for In, Ga, and Ge is often insufficient. The application of innovative solvent extraction processes is a promising approach to separate valuable metals from iron in order to make them available for an efficient recovery. In this study, we present the development of extraction methods using amine extractants for the selective separation of Fe(III) from In(III), Ga(III), and Ge(IV) in sulphate solutions. The influence of different parameters, e.g. the pH value and the composition of the organic phase, as well as possibilities to re-extract iron from the loaded organic phase, will be discussed.

3D Zinc–Organic Frameworks Based on Mixed Thiophene Dicarboxylate and 4-Amino-3,5-bis(4-pyridyl)-1,2,4-triazole Linkers : Syntheses, Structural Diversity, and Single-Crystal-to-Single-Crystal Transformations
Mahajan, Shreya; Lahtinen, Manu (American Chemical Society (ACS), 2024)In this study, for the first time two new interpenetrated 3D pillared-layer metal–organic frameworks (MOFs), namely, {[Zn(bpt)(tdc)]·dmf}n (MOF-1-Zn) and {[Zn2(bpt)(tdc)2]·2(dmf)}n (MOF-2-Zn), as well as a homochiral 3D ... -
Purification of recovered phosphoric acid by extracting aluminium with di-2-ethylhexyl phosphoric acid
Reuna, Sini; Väisänen, Ari (Springer Science+Business Media; Institute of Chemistry, Slovak Academy of Sciences, 2022)The extraction of aluminium from dilute phosphoric acid with di-2-ethylhexyl phosphoric acid (DEHPA) was optimized using response surface methodology. The optimization was based on the experimental three-level central ... -
Analysis of Lipophilic Extractives from Fast Pyrolysis Bio-Oils
Ohra-aho, Taina; Ghalibaf, Maryam; Alén, Raimo; Lindfors, Christian; Oasmaa, Anja (American Chemical Society (ACS), 2022)Fast pyrolysis bio-oils (FPBOs) originating from forest residues contain extractive-derived substances, which may form a separate, sticky layer with char particles on the surface of these bio-oils. In this study, first, ... -
