Abstract


The VO(OH)-assisted letrozole electrochemical determination has been analyzed and evaluated by theoretical point of view. The electrochemical determination is realized by a cathodic process, in which vanadium (III) oxyhydroxide plays the role of active substance and proton-electron transfer mediator. The correspondent mathematical model has been analyzed and evaluated by means of linear stability theory and bifurcation analysis. It was shown that VO(OH) may be an excellent electrode modifier for the letrozole electrochemical determination in neutral and mildly acidic pH conditions. The oscillatory behavior in neutral media is less probable than in acidic media
