99TcO4- diffusion in GMZ bentonite by through- and out-diffusion methods found that part of 99TcO4- may be reduced by Fe(II) and Da and dry density is exponential [5]. Electromigration experiments indicated that Da for selenate is range from 1.7¡Á10-11 to 6.2¡Á10-11 m2s-1 and no reduction of selenate [4]. The degree of compaction is one of the important factors that influence the diffusion behavior of radionuclides in the clay [6]. Increasing clays compacting can change hydration energy, overlapping electric double layers and clay pore size and structure [7]. The diffusion processes in compacted bentonite have interlayer space diffusion and interparticle diffusion [8]. Interlayer space diffusion is affected by change in compacted density and interparticle diffusion is primarily independent of compaction up to 1800 kg/m3 [7]. The compacted bentonite interlayer space is decreased from 3-layers to 2-layers of water at 1,600 kg/m3 and from 2-layers to 1-layer of water at 1800 kg/m3 [9, 10]. The interlayer space decreases from 1.88 nm to 1.56 nm when increasing dry density from 1300 to 1600 kg/m-3 and can be expected decrease beyond 1600 kg/m-3 [11].
