    Extractive separations of lithium isotopes with benzo-15-crown-5 and ionic liquids: a comparative study between stirred vessels and small channel contactors by Duan, C, Sun, S, Wang, H, Tarique, M, Tipper, E, Whitfield, T, Gilbert, MR, Angeli, P

    Published 2025
    “…Depending on the composition of the diluent, 4–25 % of the lithium was extracted in stirred vessels with a fractionation factor of 1.026 (±0.002) over an hour. In comparison, in the small channel contactors with 0.5 mm diameter, about 8–19 % extraction was reached in approximately 1 min with an apparent fractionation factor of 1.032 (±0.005). …”
