Water quality — Determination of calcium content-EDTA titrimetric method


This International Standard specifies a titrimetric method using
ethylenediaminetetraacetic acid (EDTA) for the determination
of the calcium content of ground waters, surface waters and
drinking waters. It can also be used for municipal and industrial
raw waters, provided they do not contain interfering amounts
of heavy metals.
The method is not applicable to sea waters and other similar
waters with a high concentration of salts. It is applicable to
waters with calcium contents ranging from 2 to 100 mg/I (0,05
to 2,5 mmol/l).
