This report describes the results of some preliminary in situ infrared spectroelectrochemical studies of cyanide specifically adsorbed on polished platinum and palladium electrode surfaces. Similar studies of this and several other pseudohalides on various metal surfaces have been conducted, but to data no work of this kind has been reported for CN- species adsorbed on the metals platinum and palladium. Also, most previous studies of this kind have been carried out in the presence of sulfate, which competes with the adsorbing anion of interest for surface sites, since sulfate may specifically adsorb to the electrode surface. This work was done in the presence of perchlorate electrolyte anion, which does not specifically adsorb on the surface to an appreciable extent. Surface-enhanced Raman SERS scattering has been used to examine cyanide adsorption on Cu and Ag in sulfate electrolyte media the results were consistent with data from infrared experiments.
