In our group, the separation of An from Ln is performed using batch-wise multi stage extraction. The condition, DGA(diglycolamide)-DTPA(diethylenetriamine-pentaacetic acid) or DGA-DTBA(diethylenetriamine-triacetic diamide),showed approximate 10 of D(Am)/D(Ln). The multi stage extraction of 10 10 of organic and aqueous phase numbers gives successfully 97% of Am with 3% of Ln in the aqueous phase.
