文摘

Sc (III) could be extracted by using the carboxyl-functionalized ILs as extractants and [Cnmim][Tf2N] as diluents. Sc (III) could be selectively separated from Y (III) and Ln (III) by simply tuning of aqueous phase pH value. Metal ions could be stripped and the ionic liquid could be reused at the same time.
