  • A REVIEW OF URANIUM SOLVENT EXTRACTION: ITS PRESENT

    amine is stronger than that of U(VI) within the extraction pH range of 0.5-2 as shown in Fig. 6. For vanadium, only V(V) can be extracted by tertiary amine at a relatively high pH such as 2. Therefore, if vanadium is present in the feed solution, its co-extraction can be controlled by reducing V(V) to V(IV) using iron powder (Crane et al. 2010).
