THE HANGING MENISCUS ROTATING-DISK (HMRD) .2. APPLICATION TO SIMPLE CHARGE-TRANSFER REACTION-KINETICS

The hanging meniscus rotating disk (HMRD) is a configuration in which the electrode material is studied without first being mounted in an in sulating mantle. It was recently shown that the hydrodynamic behavior of this system is similar to that of the conventional rotating-disk el ectrode. In this paper the applicability of this configuration to the study of simple charge transfer reaction kinetics is analyzed and some experimental data are presented. The kinetic parameters for simple ch arge transfer reactions can be obtained using the HMRD as well as on c onventional rotating-disk electrodes.
