摘要

The specific adsorption of citrate from perchloric acid electrolytes, has been investigated using in-situ FTIR spectroscopy at Au(lll) electrodes. For comparison IR spectra for formate adsorption are also presented. Clear voltammetric peaks have been observed positive of the pzc and these are shown by FTIR spectroscopy to be associated with the adsorption of citrate. Models for the surface co-ordination of the citrate anion are discussed.
