EN ISO 15681-2:2004

Water quality - Determination of orthophosphate and total phosphorus contents by flow analysis (FIA and CFA) - Part 2: Method by continuous flow analysis (CFA) (ISO 15681-2:2003)

ISO 15681-2:2003 specifies CFA methods for the determination of orthophosphate in the mass concentration range from 0,01 mg/l to 1,00 mg/l P, and total phosphorus in the mass concentration range from 0,10 mg/l to 10,0 mg/l P. The method includes the digestion of organic phosphorus compounds and the hydrolysis of inorganic polyphosphate compounds, performed either manually as described in ISO 6878 or with an integrated UV digestion and hydrolysis unit.
ISO 15681-2:2003 is applicable to various types of water (such as ground, drinking, surface, leachate and waste water). The range of application may be changed by varying the operating conditions.
This method is also applicable to the analysis of seawater, but with changes in sensitivity, by adaptation of the carrier and calibration solutions to the salinity of the samples.

Wasserbeschaffenheit - Bestimmung von Othophosphat und Gesamtphosphor mittels Fließanalytik (FIA und CFA) - Teil 2: Verfahren mittels kontinuierlicher Durchflussanalyse (CFA) (ISO 15681-2:2003)

Dieser Teil von ISO 15681 legt ein CFA-Verfahren für die Bestimmung von Orthophosphat in Massenkonzentrationen von 0,01 mg/l bis 1,00 mg/l P und Gesamtphosphor für Massenkonzentrationen von 0,1 mg/l bis 10 mg/l P fest. Das Verfahren schließt den Aufschluss organischer Phosphorverbindungen und die Hydrolyse anorganischer Polyphosphat-Verbindungen, durchgeführt entweder nach ISO 6878, [5], [6] oder mit einem integrierten UV-Aufschluss und Hydrolyse ein.
Dieser Teil von ISO 15681 ist auf unterschiedliche Wässer anwendbar (wie Grund-, Trink-, Oberflächen-wasser, Eluate und Abwasser). Der Anwendungsbereich kann durch Veränderung der Betriebsbedingungen variiert werden.
Das Verfahren kann auch auf Meerwasser angewandt werden, jedoch unter Änderung der Empfindlichkeit; die Träger- und Bezugslösungen müssen an die Salinität der Probe angepasst werden.

Qualité de l'eau - Dosage des orthophosphates et du phosphore total par analyse en flux (FIA et CFA) - Partie 2: Méthode par analyse en flux continu (CFA) (ISO 15681-2:2003)

L'ISO 15681-2:2003 spécifie des méthodes par analyse en flux continu (CFA) pour le dosage des orthophosphates dans le domaine de concentrations en masse allant de 0,01 mg/l à 1,00 mg/l (P), et pour le dosage du phosphore total dans le domaine de concentrations en masse allant de 0,10 mg/l à 10,0 mg/l (P). La méthode comprend la digestion des composés organiques du phosphore et l'hydrolyse des composés de polyphosphate inorganique, elle est réalisée soit manuellement comme décrit dans l'ISO 6878, soit avec un dispositif de digestion UV intégrée et une unité d'hydrolyse.
L'ISO 15681-2:2003 est applicable à différents types d'eau (tels que eau souterraine, eau potable, eau de surface, lixiviats et eaux usées). Il est possible de modifier le domaine d'application en faisant varier les conditions opératoires.
Cette méthode est également applicable à l'analyse de l'eau de mer moyennant une modification de la sensibilité et une adaptation des solutions vecteurs et des solutions d'étalonnage à la salinité des échantillons.
