Vitrification procedure for the extraction chromatography using porous silica covered with extractant were examined. In this method, it was expected that minor actinide (MA) were separated from high level radioactive liquid waste using extractant CMPO and/or HDEHP. In this study, vitrified adsorbent with simulated high level liquid waste were prepared and evaluated from some viewpoints of high level waste form properties. As the results, selected adsorbent were generally well vitrified and had enough chemical durability.
