- Abstract
An electroanalytical process of the quantitative determination of bivalent zinc ions over the novel Schiff bases in galvanostatic mode has been theoretically simulated. The correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It was shown that the system is efficient from both electroanalytical and electrosynthetical points of view, as the steadystate is easily stabilized. Nevertheless, the oscillatory behavior in this system is more probable than in the classic case of the sensors, based on conducting polymers and other organic materials, as there are double electric layer influences, caused by complex formation.
