The Sodium and Potassium Determination in Natural Waters

by Flame Photometry
The aim of research is to determine sodium and potassium in natural and mineral waters by a flame photo#metry method; to research structure of water samples on cations (magnesium, calcium) and anions (bicarbonate, sulfate and chloride); to research a conformity of che#mical composition of mineral waters# samples to declared indicators of ionic structure. In the course of study it is shown that the flame photometry method allows us to classify more authentically natural waters according to hydrochemical data.
Key words: surface and mineral waters, chemical composition, flame photometry.
