TKACH, Volodymyr et al. The theoretical description for CoO(OH)-assisted gabapentine electrochemical determination. Rev. colomb. cienc. quim. farm. [online]. 2019, vol.48, n.3, pp.547-556.  Epub 11-Mar-2020. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v48n3.84958.

The possibility for the use of cobalt (III) oxyhydroxide in gabapentine electrochemical determination has been evaluated. A mechanism for analyte and modifier function has been suggested. A mathematical model based in this mechanism has been developed and analyzed (by means of linear stability theory and bifurcation analysis). The theoretical evaluation confirms that the cobalt (III) oxyhydroxide may be an efficient modifier for gabapentine electrochemical determination, despite of the hybridity of its oxidation mechanism. The possibility and the causes for oscillatory and monotonic instabilities have also been investigated.

Palabras clave : chemically modified electrodes; gabapentine; cobalt (III) oxyhydroxide; electrochemical sensor; stable steady-state.
