This document specifies a method for the determination of the dissolved anions chlorate, chloride and
chlorite in water with low contamination (e.g. drinking water, raw water or swimming pool water).
The diversity of the appropriate and suitable assemblies and the procedural steps depending on them
permit a general description only.
For further information on the analytical technique, see Bibliography.
An appropriate pre-treatment of the sample (e.g. dilution) and the use of a conductivity detector (CD),
UV detector (UV) or amperometric detector (AD) make the working ranges given in Table 1 feasible.
