Separation of V from alkaline solution containing Cr using acidified primary amine N1923 with the addition of trisodium citrate
Separation and Purification Technology(2017)
Abstract
•Acidified primary amine N1923 was employed to extract and separate V from alkaline aqueous solution.•The co-extraction of V and Cr can be avoided by adding trisodium citrate.•Separation of V and Al from Cr and can be achieved even aqueous pH is high up to 13.•A two-step stripping strategy has been used to separate V and Al in the organic phase.
