Keywords:Extraction chromatography , Impregnated adsorbent, Wettability, Minor actinides

Extraction chromatography has attracted attention as a technique to recovery minor actinides (MA) from high-level radioactive liquid waste (HLLW). In this study, we carried out various surface treatment to change the polarity of TODGA adsorbent used in this process. From result of previous studies, it is found that the surface treatments significantly changed the desorption behavior of metal ions. So, we evaluated separation characteristics of simulated HLLW by using adsorbent with different wettability.
