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

Figure 8

Normalized current “𝜓” versus the reaction/diffusion parameter “𝛾” at a microelectrode modified using a conducting polymer film. The current was calculated for various values of the Biot number “𝑣” when (a) 𝛼=0.001, (b) 𝛼=0.01, and (c) 𝛼=0.1. (solid line) (23); (dotted line) (18). Solid lines are compared with points. In this figure (i) 𝑣=0.1, (ii) 𝑣=0.5, (iii) 𝑣=1, (iv) 𝑣=5, (v) 𝑣=10, (vi) 𝑣=50, and (vii) 𝑣=100.
