Approximate Analytical Solution of Nonlinear Reaction’s Diffusion Equation at Conducting Polymer Ultramicroelectrodes

Figure 9

Normalized current “𝜓” versus the reaction/diffusion parameter “𝛾” at a microelectrode modified using a conducting polymer film. The current was calculated using (21) for various values of the Biot number “𝑣” when 𝛼=10. In this figure (i) 𝑣=0.5, (ii) 𝑣=1, (iii) 𝑣=5, (iv) 𝑣=10, and (v) 𝑣=100.
