A new numerical method for theoretical analysis of polarographic catalytic current is proposed and applied to well-studied systems to prove that the method is dependable. In this method, a system of partial differential equations of diffusion is transformed to finite-difference form by using Crank–Nicolson difference scheme, and the latter is solved by using both Gauss–Seidel and successive over relaxation methods. Chemical kinetics terms in the diffusion equations is substituted by ones rewritten by three alternative procedures. The method has been applied to a system of copper(II) and hydrogen peroxide. Resulted rate constant of participating chemical reaction agrees with the rate constant obtained from bulk solution experiments. This and other results show that the method is a useful tool for theoretical analysis of catalytic waves.
