This part of ISO 10304 specifies a method for the
determination of fluoride, chloride, nitrite,
orthophosphate, bromide, nitrate and sulfate in water
with low contamination (e.g. drinking water, rain
water, ground water and surface water) in the following
ranges:
Fluoride (F): 0,Ol mg/1 to IO mg/l
Chloride (Cl): 0,l mg/l to 50 mg/l
Nitrite (NO,): 0,05 mg/l to 20 mg/l
Orthophosphate (PO,): 0,l mg/l to 20 mg/1
Bromide (Br): 0,05 mg/l to 20 mg/l
Nitrate (NO,): 0,l mg/l to 50 mg/1
Sulfate (SO,): 0,l mg/1 to 100 mg/1
NOTE 1 Anion Symbols are used without charges
throughout the text.
In certain cases, the range of application may be
changed by variations in the working conditions (e.g.
Sample volume, dilution, separating columns, preconcentration
techniques, sensitivity ranges of detectors,
etc.).
1.2 Interferences
1.2.1 Some organic acids, such as malonic acid,
malcic acid and malic acid, may interfere in the determination
of inorganic anions if they are present
in high concentrations.
1.2.2 The determination of fluoride in particular is
subject to interference by formic acid, acetic acid
and carbonate, even at low concentrations.
1.2.3 Cross sensitivity (lack of resolution) may occur
in the case of large differentes in concentration
between the anions determined (F, Cl, NO,, PO,, Br,
NO,, SO,).
1.2.4 The bromide and Phosphate anions do not
interfere in the working range specified, unless otherwise
stated.
1.2.5 In a buffered eluent (e.g. carbonate/hydrogencarbonate),
the determination will not be influenced
by the Sample pH in the range of pH 2 to
pH 9.
1.2.6 The concentration ratios given in table 1 were
checked experimentally for various representative
conditions. No interferences could be observed
when 50 ~1 of Sample volume was used for the
chromatographic analysis.
1.2.7 The information in 1.2.4 to 1.2.6 is valid only
as long as the quality requirements of the separating
