| Abstract: | A finite elements digital simulation of chronoamperometry with polymer-coated electrodes is presented. The model takes account of mass transport by diffusion and migration, and the effects of the uncompensated resistance and capacitance of the system. A graphical method for the analysis of experimental data was introduced and applied to electrodes coated with polyRu(II)(bipy)2(4-vpy)2]+PF−6. |
