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

Figure 4

Plot of normalized current “𝜓” versus the reaction/diffusion parameter “𝛾” at a microelectrode modified using a conducting polymer film. (a) (i) 𝛼=0.1,1, the current was calculated using (6) and (11) for all small and medium values of 𝛼. (b) (i) 𝛼=5, (ii) 𝛼=10, (iii) 𝛼=100, the current was calculated using (9) for all large values of “𝛼”. (c) (i) 𝛼=0.01,0.1,1 (ii) 𝛼=10, (iii) 𝛼=50, and, (iv) 𝛼=100, the current was calculated using (9) and (11) (solid line) (11); (dotted line) (6). Solid lines are compared with points.
