Criteria for the Selecting Parameters Anode Polarization Process of Substances on the Ion-Selective Electrodes Surface

Abstract

The methods of making solid-phase ion-selective electrodes, as primary converters for controlling the concentration of harmful substances during environmental monitoring of natural and technological waters, have been analyzed. The algorithm of the method of creating an ion-selective electrode with a sulfide function (IESF) is developed. The results of processes of anodic polarization of an electrode-active substance on the surface of an ion-selective electrode are given. The dependences of the time of application of the electrode-active material Ag2S at a constant current density of 6, 10, 20, 30, 40 μA/mm2 are obtained. The mathematical models of creation of the IESF with the help of one-parametric regression analysis are developed.
