This paper will attempt to present a detailed study of the intervention of an adsorption process in the expression of the faradaic impedance of an eleotrode, when acting in presence of a redox system; the general interest of this question has previously been pointed out by Gerischer, its study being especially important in relation to the behaviour of solid electrodes.

A Randles circuit has been used as a first approximation to explain the a.c. impedance of a platinum electrode in the system Cl&l-(HCIO,.,). However, in all cases the coefficient of the Warburg impedance is much higher than the theoretical value. This fact is interpreted in terms of the surface oxid

The oxidation of formic acid at a platinum electrode in 0.5 mol dm-j HsSO, was investigated by dc and cc methods. The oxidation rate of formic acid was approximately independent of the potential at potentials above about 0.35V vs. rhe, when the blocking effect of adsorbed carbon monoxide was compens
The study of the adsorption of albumin on a platinum rotating disk electrode was performed using impedance measurements. The kinetics of the adsorption was investigated by recording, during 15 min after protein addition, the variation with time of the electrochemical double layer capacitance, Cd. Th
