[1D01] Effect of Modification on Eu Sorption onto Kaolinite

*Keita Nagasawa¹, Futoshi Kanno^2,3, Kenso Fujiwara³, Terumi Dohi³, Takayuki Sasaki¹ (1. Kyoto Univ., 2. pesco, 3. JAEA)

Keywords:distribution coefficient, modified kaolinite, europium, STEM-EDS

Interaction with clay minerals has focused on migrating radioactive elements deposited by the 1F accident in soils. The Al/Si ratio of kaolinite altered by sulfuric acid was evaluated by STEM-EDS method, and the relationship with the sorption distribution coefficient of trivalent Eu was discussed.
