چکیده

The dynamic behaviour of the potentiometric carbon dioxide electrode is predicted by means of a digital simulation that considers both diffusion and reaction kinetics. The method allows for complete description of the electrode response without requiring the assumption that one of these processes can be neglected. The validity of the simulation was tested experimentally by using a commercial pC0, electrode provided with various silicone rubber and teflon membranes. The measured values are in good agreement with those of the simulation.
