Characterization of sludges - Pre-treatment for the determination of extractable ammonia using 2 mol/l potassium chloride

This European standard specifies a procedure for the determination of extractable ammonia using a 2 mol/l potassium chloride solution in raw and digested sewage sludges. The range of the method is up to 100 g/kg N assuming appropriate dilution of the potassium chloride extract in the final measurement step.
   The above wording will be modified once the round robin results are available. It may be suitable for other types of sludges, but the user should validate the method using these sludges.

Charakterisierung von Schlämmen - Vorbehandlung zur Bestimmung des extrahierbaren Ammoniums unter Verwendung von 2 mol/l Kaliumchlorid

Diese Europäische Norm legt ein Verfahren zur Bestimmung von extrahierbarem Ammonium unter
Verwendung von 2 mol/l Kaliumchloridlösung in Roh- und Faulschlamm fest. Der Bereich dieses Verfahrens
reicht bis 100 g/kg N bei angenommener angemessener Verdünnung des Kaliumchloridextrakts in der
Endmessung.
ANMERKUNG Die oben verwendete Aussage wird nach Vorliegen der Ringversuchsergebnisse modifiziert werden.
Das Verfahren kann für andere Schlammarten geeignet sein, der Anwender sollte jedoch das Verfahren unter
Verwendung dieser Schlämme validieren.

Caractérisation des boues - Prétraitement pour le dosage de l'azote ammoniacal extractible par une solution de chlorure de potassium à 2 mol/l

La présente Norme européenne prescrit un mode opératoire pour le dosage de l’azote ammoniacal extractible au moyen d’une solution de chlorure de potassium à 2 mol/l mélangée avec des boues d’eaux résiduaires fraîches et digérées. Le domaine de mesurage de la méthode a pour limite maximale 100 g/kg N en partant du principe de la dilution appropriée de l’extrait de chlorure de potassium lors de la phase finale de mesurage.
NOTE L’énoncé ci-dessus sera modifié dès que les résultats des essais interlaboratoires seront disponibles. Il se peut que la méthode puisse convenir à d’autres types de boues mais il est recommandé que l’utilisateur valide la méthode en utilisant ce type particulière de boues.
