The Mathematical Description For CoO(OH)-Assisted Hydroxylamine Electrochemical Determination in Neutral Media

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.
