Characteristics of TPDN/SiO₂-P adsorbent for MA(III) recovery

Applicability of newly developed MA(III)/RE(III) separation extractant TPDN for the extraction chromatography technology was evaluated through series of fundamental characterizations. The adsorbent selectively extract ²⁴¹Am 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 also suggested that the new adsorbent can be employed as a material for reprocessing of spent fuels. (author)
