RS ISO 7980: 1986
Water quality - Determination of Calcium and magnesium - Atomic absorption spectrometric method
Abstract

This International Standard specifies a method for the determination
of dissolved Calcium and magnesium by flame atomic
absorption spectrometry. lt is intended for the analysis of raw
and drinking waters and tan be used for waters having a
Calcium content of up to 50 mg/l and a magnesium content of
up to 5 mg/l. For samples containing higher concentrations of
Calcium or magnesium a smaller volume of the Sample must be
taken for the analysis.
When using the air/acetylene flame and the dilution factor 1 in
10, as described in 6.1, the Optimum range is 3 to 50 mg/1 for
Calcium and 0,9 to 5 mg/l for magnesium.
