Applicability of newly developed MA(III)/RE(III) separation extractant TPDN for the extractionchromatography technology was evaluated through series of fundamental characterizations. The adsorbentselectively extract $$^{241}$$Am from diluted high level liquid waste and sufficient performance for MA(III)/RE(III)separation process was confirmed. Durability and behavior in the vitrification process of the adsorbent alsosuggested that the new adsorbent can be employed as a material for reprocessing of spent fuels.
