Flame spectrometry determination of alkali and alkali-earth metals in natural, drinking and sewage waters of various mineralization levels

A set of express techniques for the flame atomic emission and atomic absorption spectrometry determination of Na, K, Mg and Ca in natural, drinking and sewage waters of various mineralization levels is developed. It is shown that addition of cesium chloride to the solutions to be analyzed as well as a correct choice of a flame allows determination of these cations at presence of excess of accompanying ions. Results of analysis demonstrated no significant systematical errors. The developed techniques allow determination of Na, K, Mg and Ca in the concentration range 5.0 - 30000, 0.1- 500, 0.3-2000 and 3.0-30000 mg l-1, respectively. The relative standard deviations were 0.01-0.04.

Keywords: flame spectrometry alkali and alkali-earth metals natural, drinking and sewage waters
