摘要：

Multisweep cyclic voltammograms (MSCVS) of different clay-modified electrodes exposed to Cr(bpy)3(3+) are obtained. The MSCVs of these fully swollen films depend upon the cation exchange capacity of the clay, as predicted from two-step kinetic theory. Furthermore, the electrolyte anion can interfere with a simple diffusion ion exchange process. The influx of material is consistent with porosity changes in the films. These porosity changes do not conform to simple double-layer predictions for the spacing between two charged platelets.
