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. Table 1 — Working ranges of the analytical method Anion Working range mg/la Detection Chlorate 0,03 to 10 CD Chloride 0,1 to 50 CD Chloriteb 0,05 to 1 CD 0,1 to 1 UV; λ = 207 nm to 220 nm 0,01 to 1 AD; 0,4 V to 1,0 V a The working range is restricted by the ion-exchange capacity of the columns. If necessary, samples can be adjusted to this range by dilution. b The minimum working range for chlorite of 0,05 mg/l was obtained using calibration checks, but the interlaboratory trials (see Table A.4) showed that it is difficult to obtain this with sufficient accuracy, and only if taking great care.
