Water quality - Determination of adsorbable organically bound halogens (AOX) (ISO 9562:2004)
ISO 9562:2004 specifies a method for the direct determination of an amount of usually 10 micrograms per litre in water of organically bound chlorine, bromine and iodine (expressed as chloride) adsorbable on activated carbon.
This method is applicable to test samples with concentrations of inorganic chloride ions of less than 1 g/l. Samples with higher concentrations are diluted prior to analysis.
This method is also applicable to samples containing suspended solids where halogens are adsorbed onto the solid matter (e.g. insoluble halides). Filtration of the sample before analysis allows the separate determination of dissolved and particulate adsorbable organically bound halogens (AOX).
Filtered samples with high inorganic chloride content can be analysed by a modified method [dissolved adsorbable organically bound halogens after solid phase extraction in waters with high salt content (SPE-AOX)]. However, results obtained by this modified method can differ significantly from those of the required method.
Wasserbeschaffenheit - Bestimmung absorbierbarer organisch gebundener Halogene (AOX) (ISO 9562:2004)
Diese Internationale Norm legt ein Verfahren fest für die direkte Bestimmung einer Massenkonzentration von üblicherweise 10 µg/l organisch gebundener Halogene Chlor, Brom und Iod (angegeben als Chlorid), die an Aktivkohle adsorbierbar sind.
Dieses Verfahren gilt für Konzentrationen < 1 g/l an anorganischen Chlorid-Ionen in der Analysenprobe (siehe 9.2). Proben mit höheren Konzentrationen werden vor der Analyse verdünnt.
Dieses Verfahren gilt auch für Proben mit suspendierten Stoffen, bei denen an den Feststoffen adsorbierte Halogene (z. B. ungelöste Halogenide) mit erfasst werden. Eine Filtration der Probe vor der Analyse erlaubt eine getrennte Bestimmung von gelösten und partikulären adsorbierbaren organisch gebundenen Halogenen (AOX).
Filtrierte Proben mit einem hohen Gehalt an anorganischem Chlorid können nach dem modifizierten Verfahren (SPE-AOX) (siehe Anhang A) analysiert werden. Die Ergebnisse können sich jedoch signifikant von denen des im Hauptteil festgelegten Verfahrens unterscheiden.
Qualité de l'eau - Dosage des composés organiques halogénés adsorbables (AOX) (ISO 9562:2004)
L'ISO 9562:2004 spécifie une méthode pour le dosage direct de la quantité de composés organiques contenant du chlore, du brome et de l'iode (exprimée en chlorure) adsorbables sur charbon actif en concentration régulière de plus de 10 microgrammes dans l'eau.
La méthode est applicable aux échantillons d'essai présentant des concentrations en ions chlorure inorganiques inférieures à 1 g/l. Les échantillons présentant des concentrations supérieures sont dilués avant l'analyse.
La méthode est également applicable aux échantillons contenant des matières en suspension, où les halogènes sont adsorbés sur les matières solides (par exemple les halogénures insolubles). Une filtration de l'échantillon avant de procéder à l'analyse permet le dosage séparé des AOX dissous et des AOX particulaires.
Les échantillons filtrés contenant une teneur élevée en chlorure inorganique peuvent être analysés en utilisant une méthode modifiée [composés organiques halogénés adsorbables dissous après extraction sur phase solide (SPE-AOX) dans les eaux à teneur élevée en sel]. Cependant, les résultats obtenus par cette méthode modifiée peuvent différer significativement des résultats obtenus par la méthode requise.
