- Abstract
By means of the theoretical mechanistic analysis, the possibility of the use of vanadium oxyhydroxide as electrode modifier for saccharin electrochemical determination has been evaluated. The electroanalytical process is realizing by a cathodic route. The correspondent mathematical model has been analyzed by means of the linear stability theory and bifurcation analysis. The analysis of the model has shown that the vanadium oxyhydroxide is an efficient electrode modifier for saccharin electrochemical detection in pH sufficiently low to maintain the process, but insu- fficiently acidic to dissolve the oxyhydroxide. The causes for the oscillatory and monotonic instabilities have also been derived.
