✦ Synopsis

The feasibility of studying adsorption processes by following changes in the lateral resistance of a thin-film platinum electrode has been investigated. The principal difficulty associated with this technique is to correct for the parallel conduction through the electrolyte. A theoretical treatment of this problem indicates that, providing the slope of the current-potential relation for

the electrode reaction is small, a satisfactory correction for these co-conduction effects may be applied.

The method has been used to study the adsorption of hydrogen, oxygen, thallium, chloride and bromide on platinum. The results are in genera1 accord with those obtained by other methods.
