TKACH, Volodymyr V. et al. The mathematical description of the function of a novel acridinic derivative in the electroanalytical detection of total gallic acid content in carob. Rev. colomb. cienc. quim. farm. [online]. 2018, vol.47, n.3, pp.441-451. ISSN 0034-7418. https://doi.org/10.15446/rcciquifa.v47n3.77375.
The possibility of the use of the novel acridinic derivative, containing an electron donor moiety in the total gallic acid content determination in carob gum has been evaluated by means of a theoretical analysis. The correspondent mathematical model has been analyzed by linear stability theory and bifurcation analysis. It was shown that the phosphazoic acridine derivative may serve as an efficient electrode modifier for electroanalytical determination of the total content of gallic acid in carob. The causes for the oscillatory and monotonic behavior have also been stipulated.
