Title: Transport of Iodide Ion in Compacted Bentonite Containing Ag{sub 2}O - 12111

Abstract

Observations of the transport of iodide through compacted bentonite containing Ag{sub 2}O as additive and that without additive were made. Compacted bentonite samples with densities of 1.41 g/cm{sup 3} and 1.60 g/cm{sup 3} were used in the experiment. The amount of Ag{sub 2}O added to the compacted bentonite was in the range of 0.0064 ∼ 0.0468 wt/wt%. Two diffusion solutions were used: one in which iodide ion was dissolved in demineralized water (pure iodide solution), and one in which iodide ion was dissolved in 0.1 M NaCl solution (0.1 M NaCl-iodide solution). Experimental results confirmed that iodide ion was transported by the diffusion process in the compacted bentonite containing Ag{sub 2}O as well as in the compacted bentonite without Ag{sub 2}O. The time-lag of diffusion of iodide ion in the compacted bentonite containing Ag{sub 2}O is larger than that in the compacted bentonite without Ag{sub 2}O. The increase of the time-lag of diffusion was observed in pure iodide ion solution as well as in 0.1 M NaCl-iodide solution. The apparent diffusion coefficient of iodide ion in the compacted bentonite containing Ag{sub 2}O was smaller than in the compacted bentonite without Ag{sub 2}O. The effective diffusion coefficient decreased as the amountmore » of Ag{sub 2}O in the compacted bentonite increased. (authors)« less
