Water quality - Determination of mercury - Method using atomic absorption spectrometry

This European Standard specifies two methods for the determination of mercury. For the method described in Clause 4, tin(II) chloride is used as the reducing agent. For the method given in Clause 5, sodium borohydride serves as the reducing agent. The choice of method depends on the equipment available and the matrix (see Clause 3). Both methods are suitable for the determination of mercury in water, for example in drinking, ground, surface and waste waters, in a concentration range from 0,1 µg/l to 10 µg/l. Higher concentrations can be determined if the water sample is diluted. Lower concentrations in the range of 0,001 µg/l to 5 µg/l can be determined if special mercury analysers with an optimised instrument are used or if atomic fluorescence spectrometry is applied (see EN 13506 or ISO 17852).

Wasserbeschaffenheit - Bestimmung von Quecksilber - Verfahren mittels Atomabsorptionsspektrometrie

Diese Europäische Norm legt zwei Verfahren zur Bestimmung von Quecksilber fest. Als Reduktionsmittel wird
im Verfahren nach Abschnitt 4 Zinn(II)chlorid, im Abschnitt 5 Natriumtetrahydroborat eingesetzt. Die Wahl des
Verfahrens richtet sich nach der zur Verfügung stehenden Ausrüstung und der Matrix (siehe Abschnitt 3).
Beide Verfahren eignen sich zur Bestimmung von Quecksilber in Wässern, beispielsweise in Grund-
Oberflächen- und Abwässern im Konzentrationsbereich von 0,1 µg/l bis 10 µg/l. Höhere Konzentrationen
lassen sich nach entsprechender Verdünnung der Wasserprobe bestimmen. Niedrigere Konzentrationen im
Bereich 0,01 µg/l bis 1 µg/l können bestimmt werden, wenn spezielle Quecksilber-Analysatoren mit
optimierten Instrumenten eingesetzt werden.

Qualité de l'eau - Dosage du mercure - Méthode par spectrométrie d'absorption atomique

La présente Norme européenne spécifie deux méthodes de dosage du mercure. Dans la méthode décrite dans l’article 4, le chlorure d’étain (II) est utilisé comme réactif de réduction alors que dans celle décrite à l’Article 5, c’est le borohydrure de sodium qui sert de réactif de réduction. Le choix de la méthode dépend de l’équipement disponible et de la matrice (voir Article 3). Les deux méthodes conviennent pour le dosage du mercure dans l’eau, par exemple l’eau potable, les eaux souterraines, les eaux de surface et les eaux usées, dans une plage de concentration allant de 0,1 g/l à 10 g/l. Des concentrations plus élevées peuvent être déterminées si l’échantillon d'eau est dilué. Si l’on utilise des analyseurs spécifiques du mercure optimisés ou une méthode par spectrométrie de fluorescence atomique (voir l'EN 13506 ou l'ISO 17852), il est possible de doser le mercure à des concentrations plus faibles dans la plage de 0,01 g/l à 1 g/l.

EN 1483:2007 (E) 3 Foreword This document (EN 1483:2007) has been prepared by Technical Committee CEN/TC 230 “Water analysis”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007, and conflicting national standards shall be withdrawn at the latest by October 2007. This document supersedes EN 1483:1997. NOTE This revision of EN 1483:1997, without stating details, takes into account new state of the art methods. This revision also describes continuous flow methods whilst the batch tests have been deleted as they are no longer used. In Annex A.1, a bromate bromide conservation/digestion step is included, thus allowing to avoid potassium permangante resp. potassium chromate. According to the
