Specular Reflectance Studies of Bromide Adsorption on Gold.

Abstract

Specular reflectance changes have been used to examine specific adsorption of bromide on gold in the presence of a large excess of supporting electrolyte (NaF) which is not specifically adsorbed. A linear relation has been demonstrated between the relectance changes and the surface excess of bromide through the examination of the time dependence of the reflectance under conditions where the rate of adsorption of the bromide is diffusion controlled and hence known. The adsorption isotherms have been found to follow Temkin behavior. The electrosorption valencey has been evaluated from the charge and surface excess at constant potential and found to be -0.49 to -0.59, depending on the potential.
