Experimental and modeling study on long-term alteration of compacted bentonite with alkaline groundwater

Yamaguchi, Tetsuji; Sakamoto, Yoshifumi; Akai, Masanobu; Takazawa, Mayumi; Iida, Yoshihisa; Tanaka, Tadao; Nakayama, Shinichi

Physics and Chemistry of the Earth, 32(1-7), p.298 - 310, 2007/00

 Times Cited Count:44 Percentile:72.77(Geosciences, Multidisciplinary)

Dissolution rate of montmorillonite, diffusivity of hydroxide ion and permeability coefficient in compacted sand-bentonite mixtures were experimentally determined and formulated. A coupled mass-transport/chemical-reaction code was developed to predict variation in permeability of engineered bentonite barrier with alkaline fluid by using the formulae.

Sorption Behavior of Cs onto Bentonite Colloid

Iijima, Kazuki; Tomura, Tsutomu*; Masuda, Tsuguya*

Proceedings of 2nd International Meeting on Clays in Natural and Engineered barriers for Radioactive Waste Confinement (TOURS 2005) (CD-ROM), p.607 - 608, 2005/00

The batch sorption and desorption experiments of Cs onto bentonite colloid were carried. The sorption data was fitted to Freundlich isotherm and distribution coefficient was obtained as about 20 m$$^{3}$$/kg, which is larger than that of powdered bentonite. It might be caused by the difference of the shape of bentonite. In the desorption experiment, almost same distribution coefficient was obtained so that, at least, 30% of Cs was sorbed reversibly.
