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

Figure 7

Plot of Normalized substrate concentration “𝑢” at a microelectrode modified with a polymer film as a function of “𝜌”. The concentrations were computed using (20) for various values of the Biot number “𝑣” when 𝛾=0.1 and for (a) 𝛼=5, (b) 𝛼=10 and (c) 𝛼=50. In this figure (i) 𝑣=0.1, (ii) 𝑣=0.5, (iii) 𝑣=1, (iv) 𝑣=5, (v) 𝑣=10, (vi) 𝑣=50.
