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

Figure 2

Plot of normalized substrate concentration “𝑢”at a microelectrode modified with a polymer film as a function of “𝜌”. The concentrations were computed for various values of the reaction diffusion parameter “𝛾” when (a) 𝛼=0.001, (b) 𝛼=0.01, (c) 𝛼=0.1, and (d) 𝛼=1. (solid line) (10); (dotted line) (5). Solid lines are compared with points. In this figure (i) 𝛾=0.1, (ii) 𝛾=1, (iii) 𝛾=10, and (iv)𝛾=100.
