Abstract
The adsorption of benzoic acid on platinum, gold, copper, and silver e lectrodes has been studied by radiometric and voltammetric methods. Th e adsorption of benzoic acid is a reversible process on Au, Cu, and Ag electrodes. On Pt electrode the process is partly irreversible. The a dsorption can be described by the Frumkin-type isotherm. The influence of water adsorption on the Gibbs energy of adsorption has been discus sed. The rate of adsorption follows the Roginsky-Zeldovitsh equation a nd is controlled by the rate of surface processes.
