Mass transfer in the cone and plate system and its applications
MetadataShow full item record
Mass transfer and electrode reaction for an electrochemical process in the cone and plate geometry was studied. Analytical expressions for the concentration profiles and current distribution were obtained for the following four cases: (i) unsteady state electrolysÃ®s below limiting current conditions; (ii) unsteady state electrolysis at limiting current conditions; (iii) steady state electrolysis below the limiting current conditions; (iv) steady state electrolysis at limiting current conditions. The reaction order, the reaction rate constant, the electrode reaction transfer coefficient, the number of electrons involved, and the diffusion coefficient can be determined by solving for the current necessary to maintain a constant potential difference across the electrodes (potentiostatic method).
