When rubber dissolved in toluene was used as a binding material of graphite powder, the mechanical robustness of the carbon paste was guaranteed by the fast volatility of the solvent immediately after electrode construction. This characteristic of the rubber solution met qualifications for practical use of carbon paste electrodes and enabled the design of a new enzyme electrode bound with EPDM. In order to confirm whether the electrode shows quantitative electrochemical behaviors or not, its kinetic parameters, e. g. the symmetry factor (0.2), the exchange current density (3.66 μA/cm2), the capacity of the double layer (2.0 × 10-5 F), the Michaelis constant (4.39 × 10-3 M), the diffusion coefficient of substrate (2.58 × 10-12 cm2/sec), the time constant (0.018 sec) and other factors were investigated.
