Monomolecular and multilayers of ferrocene derivatives have been deposited on or bonded

to electrodes and examined by XPS. In many cases the preparation leaves the modified surface

in an oxidized, ferricenium state. Evidence supporting this and possible oxidative mechanisms is

discussed.

This work is concerned with the investigation of galvanoluminescence at the interface

metal-oxide-electrolyte during DC anodization of very pure aluminum foils in boric acid-borax

solution at constant current. The rate of anodic film formation, the quantitative relations

between anode voltage and luminescence intensity as well as the shape of optical emission

spectra at different voltages are obtained for annealed and unannealed Al samples. It is found

that the previous thermal treatment has great influence on anodization and luminescence

processes.

Adsorption in electrochemical systems is discussed by comparing and contrasting it with

adsorption at the gas-metal interface. Some particular problems in the study of solid surfaces

are considered.
