Originální abstrakt

A problem of electrochemical behavior of different topologies of thick-film electrochemical sensors is described in this paper. In this paper, there were examined properties of working and reference electrodes by output current response and peak potential using DC voltammetry and potassium ferro-ferricyanide solution. For this purpose, there were made several electrodes containing different sized working electrode area made of Ag, Au and Pt. The influence of working electrode area size of common electrochemical sensor to output current response was measured against commercial Ag/AgCl reference and Pt auxiliary electrode in three electrode system. As we supposed, the results confirmed the Levic equation for solid electrodes. The influence of Ag reference electrode area size of common electrochemical sensor to output current response and to peak potential was measured against commercial Au working and Pt auxiliary electrode in two and three electrode system of measurement. The results confirmed presumption that for small sized thick-film sensors, the three-electrode arrangement is more accurate and reproducible than two-electrode system.
