Double Layer Studies using Depolarizers as Probe - A Reassessment

The influence of the double layer on mercury electrodes has been assessed by examining a large number of depolarizers and supporting cations. Cross-analysis of the results shows that, besides the Frumkin mechanism, ion-pairing can be also a significant factor, either by increasing the local concentration of the depolarizer, or by enhancing its intrinsic electroactivity. These effects are correlated to various other types of behavior (electrolytes, colloids, exchangers) in terms of a common charge interaction model taking into account structural changes brought to the solvent

Analyses inorganiques avec emploi conjugué du polarographe et de la colonne d'échange

I. Analytical potentialities of the simultaneous use of exchange and polarographic techniques are briefly discussed. II. Isolation of traces of zinc from cadmium may be performed successfully by use of Dowex 50 exchanger and ammonium citrate buffer as eluting agent, under described conditions. The limiting sensitivity of the method is about 0.002 % Zn in Cd. 0.1% of Zn is determined with an accuracy of 2%. Copyright © 1954 Wiley‐VCH Verlag GmbH & Co.
