Introduction. Using method of chronoionometry and ion-selective electrodes makes it possible to determine quickly the concentrations of chemical elements, which allows you to assess the quality of drinking water and the ecological condition of the environment.

The purpose of the paper is to apply the developed method of chronoionometry to measure the concentrations of fluoride, nitrate, ammonium in drinking water and to assess the accuracy of measuring concentrations.

Methods. Chronoionometric method of chemical analysis uses the principles of direct potentiometry to measure the concentrations of chemical elements.

Results. Methods for detection the concentrations of fluorine, nitrates, ammonium in drinking water were obtained and tests were performed in model aqueous solutions using the device of inversion chronopotentiometry “Analyzer SCP”, which testify to the compliance of measurement errors with metrological normative values.

Conclusions. Improved analytical system “Analyzer SCP” to determine the concentration of 20 chemical elements (Hg, As, Pb, Cd, Cu, Zn, Sn, Ni, Co, Se, Mn, I, Cr, Fe, K, Na, Ca, F, NO3, NH4) in aqueous solutions by inversion chronopotentiometry and chronoionometry, which is sufficient for ecological assessment of drinking water quality and environmental objects. The use of a new method of chronoionometry significantly expands the functionality of the device of inversion chronopotentiometry, increases the reliability and accuracy of measuring the concentrations of chemical elements.

Keywords: chronoionometry method, concentration, of fluoride, nitrate, ammonium, ion-selective electrode, inversion chronopotentiometry, drinking water.
