SUCRALOSE CoO(OH)-ASSISTED ELECTROCHEMICAL DETECTION IN ALKALINE MEDIA. THE THEORETICAL ANALYSIS OF AN INTERESTING POSSIBILITY

The sucralose electrochemical determination, assisted by cobalt (III) oxyhydroxide, has been theoretically evaluated. The mathematical model, describing the electroanalytical process, has been developed. The analysis of the model by linear stability theory and bifurcation analysis has shown that CoO(OH) may be applied as an efficient electrode modifier in the sucralose determination in neutral and lightly alkaline media. The electrochemical response has to be clear and easy to interpret. The oscillatory and monotonic instabilities may occur due to double electric layer influences of the electrochemical process
