Toward the development of a practical separation method for trivalent actinides and lanthanides, we used extraction chromatography with alkyl-pyridinedicarboxyamides as the extractant. The results confirmed that the performance degradation of the adsorbent caused by contact with HNO $_{3}$ and/or irradiation with rays would be very small during the operation of column chromatography. The optimal conditions for the column separation were also determined: eluent, 5M HNO $_{3}$ ; flow rate, 0.1 mL/min.
