吸着特性が陽イオン移動に与える影響について

In order to clarify influence of adsorption properties on cation transfer in sorbing porous media, a cation transfer test was performed with three kinds of porous media（glass beads, sand and clay）having different adsorption properrties.
From the results obtained, mass transfer in glass beads was independent of concentration, flux in the solution and material size. Mass transfer in sand was influenced only by concentration in the solution. Mass transfer in clay was affected by concentration and flux in the solution. It was shown that a solution phase had to been divided between a mobile phase and an immobile phase to describe mass transfer in clay.
