In this paper, mathematical model of Martens and HallAnalytical chemistry 66, 2763-27701994 for animmobilized oxidase enzyme electrode is discussed. The model involves the systemof non-linear reaction diffusion equations under the steady state conditions. Asimple and closed-form of approximate analytical expressions for the concentrationsof the immobilization of three enzyme substrates has been derived by solving the system of non-linear reactiondiffusion equations using new approach of homotopy perturbation method. Approximate polynomial expression of concentration of substrate, oxygen and oxidizedmediator and current was obtained in terms of the Thiele moduli and the smallvalues of parameters Bs, Bo and Bm normalized surface concentration of substrate, oxygenand oxidized mediator. Furthermore, in this work the numerical simulation of theproblem is also reported using Matlab program. An agreement between analytical expressionsand numerical results is noted.
