Sažetak

The present paper summarises the electrochemical behaviour
of 4-benzothiazolylazo-N-thiocarbamoyl-3,5-dimethyl pyrazoles.
The reduction of above compounds takes place in a single 2e wave
at d.m.e. corresponding to the reduction of azo group. All the compounds give irreversible waves at pR values pR > 3.0 and
reversible waves at pR values pR < 3.0. All waves are diffusion
controlled and half-wave potentials pR dependent. The effect of
substituents has been determined quantitatively by the application
of Hammett equation. A plausible mechanism has been suggested
for the electrodeprocess. Furthermore, the effect of ionic-strength,
cations, anions and solvent composition has been studied in terms
of the changed electrical double layer.
