Theoretical Description for Orellanine Electrochemical Determination and Electropolymerization in the Presence of Hydroquinones, Assisted by CuS Nanoparticles

The theoretical description for orellanine electrochemical determination and electropolymerization, assisted by CuS nanoparticles, deposited over a graphene surface, is given. Taking into account the orellanine similarity to hydroquinonic compounds, alongside with their higher oxidation potential, copper sulfide nanoparticles, paired with copper (III) sulfohydroxide are used. Orellanine polymerization is also promoted, yielding a natural-based conducting polymer with interesting catalytical properties. The analysis of the correspondent mathematical model confirms the efficiency of the system. The linear dependence between the electrochemical parameter and concentration is easy to obtain and maintain. On the other hand, the oscillatory and monotonic instabilities in this system will be more probable than for hydroquinone compound determination.
