The Mathematical Description of Allopurinol Electrochemical Determination, Assisted by VO2+/V02+ Redox Pair in Acidic Solutions

Abstract

The possibility of allopurinol electrochemical detection, assisted by pervanadylvanadyl redox pair, has been evaluated 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 the steady-state stability in this system is maintained easily. The electroanalytical process is diffusion-controlled. The oscillatory behavior in this system is more probable than for general case, due to the presence of electrostatic and DELinfluencing factors.
