• The d.c. polarographic reduction of a redox polyelectrolyte, poly[(<I>p</I>-methylbenzyl)viologen] dibromide, in the presence of cadmium sulfate salt demonstrated two well-defined, irreversible diffusion-controlled cathodic waves corresponding to the reduction of protonated form as well as the cadmium complex of the polyelectrolyte in aqueous buffers (pH 2.00–6.00). No wave was observed due to the reduction of the unprotonated form of the polymer in the present instance, however, another ill-defined wave of irreversible nature was emerged at relatively higher negative potential presumably because of the catalytic evolution of hydrogen, at the dropping mercury electrode. An attempt has been made to correlate these results in terms of cadmium ion interaction with the polyelectrolyte during the course of electrode processes.
