Abstract :
The possibility of hydroxylamine electrochemical determination over a CoO(OH)-
modified electrode, accompanied by complex-formation, has been studied from the theoretical point
of view. The correspondent mathematical model has been developed and analyzed by means of
linear stability theory and bifurcation analysis. It was shown that CoO(OH) may be applied
as an efficient electrode modifier in the detection of hydroxylamine in neutral and slightly alkaline
media. The electrochemical response has to be clear and easy to interpret. The possibility of the
oscillatory and monotonic instabilities has also been verified.
