Solvent extraction of scandium from chlorination system with EHPAEH [PDF]

open access: yesMATEC Web of Conferences, 2019
The extraction of scandium from hydrochloric acid media with EHPAEH is investigated. Fe3+ in synthesized solution would reduce the purity of scandium, therefore, N235 is selected as extractant for separating Fe3+ and Sc3+.
