Distribution of Cs and Am in the solution-bentonite colloids-granite ternary system; Effect of addition order and sorption reversibility

Iijima, Kazuki ; Tomura, Tsutomu*; Tobita, Minoru*; Suzuki, Yasuyuki*

Distribution behavior of Cs and Am in the synthetic groundwater-bentonite colloids-granite ternary system was investigated. Radionuclide sorbed onto the bentonite colloids is desorbed by addition of granite, indicating that the sorption of Cs and Am onto the bentonite colloids are reversible. The sorption model based on cation exchange and surface complexation reaction considering high edge site density for bentonite colloids is applicable to explain the sorption behavior of Am and Cs in the ternary system.
