The purpose of the paper is to develop an algorithm for processing data measuring alkali and alkaline earth metal concentrations by a new electrochemical method of chronoionometry, based on the use of the principles of direct potentiometry and ion-selective electrodes on the inversion chronopotentiometry device. Results. The method of chronoionometry was developed and testing was performed on the device of stripping chronopotentiometry "Analyzer SCP" for determining the concentrations of potassium, sodium and calcium in model aqueous solutions. Analytical system "Analyzer SCP" includes five electrochemical research methods: the method of stripping chronopotentiometry (SCP); pulse method SCP (PSCP); differential pulse method SCP (DPSCP); oxidative pulse method SCP (OPSCP); chronoionometric method (CHI). The algorithm for processing concentration measurement data by chronoionometry makes it possible to select specific potential measurements and not take into account unstable values. Measurements are performed by the method of multiple standard additives to ensure controllability of the analysis results.
