Testing water. Determination of anions (F-, Cl-, NO2-, NO3-, BR-, po4 3-, SO4 2-) by ion chromatography.

La présente norme expérimentale s'adresse aux laboratoires ayant à doser un certain nombre d'anions dans les eaux. Elle décrit une méthode adaptée au besoin des contrôles de routine de la qualité des eaux (dosage au niveau du mg/l) qui, en conséquence, ne correspond pas aux performances optimales qui peuvent être obtenues, notamment pour les seuils de détection, par la chromatographie ionique.

Water quality - Determination of dissolved anions by liquid chromatography of ions - Part 1 : determination of bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulfate

<p>ISO 10304-1:2007 specifies a method for the determination of dissolved bromide, chloride, fluoride, nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste water, leachates and marine water by liquid chromatography of ions. </p> <p>The lower limit of application is greater than or equal to 0,05 mg/l for bromide and for nitrite, and greater than or equal to 0,1 mg/l for chloride, fluoride, nitrate, orthophosphate, and sulfate. The lower limit of application depends on the matrix and the interferences encountered.</p> <p>The working range may be expanded to lower concentrations (e.g. greater than or equal to 0,01 mg/l) if an appropriate pre‑treatment of the sample (e.g. conditions for trace analyses, pre‑concentration technique) is applied, and/or if an UV detector (for bromide, nitrate and nitrite) is used.</p>
