Abstract

Experimental studies have been performed for the simultaneous potential orcurrent oscillations occurring both on cathode and anode in the IO3-/Fe(CN)(6)(4-) system. The combined oscillator exhibits very different behavior from that of the individual oscillators on each electrode owing to the different waveforms and incommensurate oscillating frequencies of the individualoscillators. The potential oscillation of the combined oscillator is essentially a sum of those of the individual oscillators for the mixed system, whereas the sum coming from the single systems is slightly different, mainlydue to the difference in ionic strength between the single system and the mixed system. The separate current oscillators also seem to interfere with each other, probably through the restricted distribution of the applied voltage in both electrodes and the ohmic drop in addition to the effect of ionic strength (C) 2000 Elsevier Science S.A.
