Resumen:
Experimental
data for the behaviour of a rotating disc electrode with a hanging electrolyte
column of varying height are presented. A correlation involving the limiting
current density, the rotating speed,and the physicochemical properties of the
solution is established. Te macroscopic effective copper electrodeposit
thickness distribution is determined. Results obtained for different electrode
designs are discussed in terms of an additional flow of reactant, and an
apparent change in the effective electrode area caused by liquid column
contraction. From the results the most suitable experimental conditions for the
application of the rotating disk electrode with hanging column of electrolyte
to electrochemical kinetic studies can be found.
