Method development for determination and recovery of rare earth elements from industrial fly ash
Perämäki, Siiri (University of Jyväskylä, 2014)Rare earth elements (REE) are important in numerous high technology applications and in addition their supply risk is high, which gives rise to studying new sources for rare earth elements. Rare earth element concentrations ... -
Alkyl-Substituted Aminobis(phosphonates) : Efficient Precipitating Agents for Rare Earth Elements, Thorium, and Uranium in Aqueous Solutions
Virtanen, Emilia J.; Perämäki, Siiri; Helttunen, Kaisa; Väisänen, Ari; Moilanen, Jani O. (American Chemical Society (ACS), 2021)The efficient and environmentally sustainable separation process for rare earth elements (REE), especially for adjacent lanthanoids, remains a challenge due to the chemical similarity of REEs. Tetravalent actinoids, thorium, ... -
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 ... -
