Keywords:Bentonite, Copper, Diffusion

In this study, electro-migration experiments were conducted as parameters of applied electric potential and bentonite dry density for obtaining the diffusion of copper ion in bentonite (Kunipia F). As a result, the apparent diffusion coefficient became almost constant regardless of the applied electric potential, and the values were on the order of 10-12[m2/s].
