Water quality —Calcium and magnesium content — Atomic absorption spectrometric method
Description
This International Standard specifies a method for the determination of dissolved calcium and magnesium by flame atomic absorption spectrometry. It is intended for the analysis of raw
and drinking waters and can be used for waters having a calcium content of up to 50 mg/I and a magnesium content of up to 5 mg/I. For samples containing higher concentrations of
calcium or magnesium a smaller volume of the sample must be taken for the analysis.
