The Mathematical Model for Thiabendazole Electrochemical Determination in Pharmaceutical Formulations, Biological Liquids and Food Products

Abstract

In this work, the electrochemical determination of thiabendazole in pharmaceutical formulations, biological liquids, and food has been described using a mathematical model, which was thereby analyzed using linear stability theory and bifurcation analysis. Three scenarios, including Noxidation, S-oxidation, and electropolymerization, have been included in the model. The model analysis shows that, despite the presence of the electropolymerization scenario and the increase in the probability of oscillatory behavior, the electroanalytical process, performed anodically on copper sulfide nanoparticles, is efficient and may be used for both electrochemical determination and excess removal of thiabendazole. As for poly(thiobendazole), it is suitable for the determination and removal of heavy metal ions.
