New quantitative methods of electrode evaluation under continuous voltammetric conditions

Abstract

An original method for the quantitative description of voltammograms under different conditions of multisensory analysis and the elaboration of a new generation of high-sensitivity “electronic tongues” is suggested.

Description of Complex Fluids Electrochemical Data in the Frame of Percolation Model

“…In the context of the modern speculations considering the surface state as a specific dynamical nanoreactor , the proposed model allows to understand deeper the role of each current participating in the percolation process and the fractal structure of the surface that originates the desired percolation channel connecting the electrodes. In particular, the proposed model allows understanding the role of the background currents that can contain additional information about the nature of multicomponent complex fluid . Therefore, using as an object of the pure olive oil we put forward the following questions and demonstrate the ways of their solution.…”

Application of the Discrete Geometrical Invariants to the Quantitative Monitoring of the Electrochemical Background

“…When the number of the measurements are rather small there are mathematical methods that take into account the drift of the detected signal in time [6] while for the multi-cycling sensor(the number of the measurement cycles are large, M ≥ 1000) the mathematical methods related to quantitative monitoring of these sensors in time are not well developed. In this case, the electrode surface is changed significantly and can reflect the different stages of its electrochemical transformations [7,8]. It is known that in the inverse voltamperometry for the receiving of the reproducible working electrode surface, it is polarized in the cycling regime for the chosen potential range.…”
