(Main)Characterization of sludges - Determination of total phosphorus
Characterization of sludges - Determination of total phosphorus
This European Standard specifies a procedure for complete digestion of raw/digested sludge, suitable for the subsequent determination of phosphorus.
Phosphorus in environmental samples can be present in many forms. This method of pre-treatment enables the analyst to determine all forms - i.e. total phosphorus, by quantitative oxidation yielding an aqueous solution of orthophosphate which should be analysed for phosphate according to method EN ISO 6878, EN ISO 10304-2 or an equivalent validated method.
The range of the method is up to 50 g/kg P assuming appropriate dilution of the digest in the final measurement step.
Charakterisierung von Schlämmen - Bestimmung von Gesamtphosphor
Diese Europäische Norm legt ein Verfahren zum vollständigen Aufschluss von Roh-/Faulschlamm für die
anschließende Bestimmung von Phosphor fest.
ANMERKUNG Phosphor kann in Umweltproben in vielen Verbindungen vorhanden sein. Dieses Verfahren der
Vorbehandlung ermöglicht es dem Analytiker alle Verbindungen zu bestimmen � d. h. Gesamtphosphor durch
quantitative Oxidation unter Bildung einer wässrigen Orthophosphatlösung, die auf Phosphat gemäß dem Verfahren nach
EN ISO 6878, EN ISO 10304-2 oder einem äquivalenten validierten Verfahren analysiert werden sollte.
Das Verfahren ist anwendbar bis zu 50 g/kg P bei geeigneter Aufschlussverdünnung in der Endmessung.
Caractérisation des boues - Dosage du phosphore total
La présente Norme européenne définit un mode opératoire pour la minéralisation complète de la boue
brute/digérée, applicable pour la détermination ultérieure de la teneur en phosphore.
NOTE Le phosphore dans des échantillons prélevés dans l�environnement peut se présenter sous plusieurs formes.
La présente méthode de prétraitement permet à l�analyste d�en déterminer toutes les formes (c�est-à-dire la teneur en
phosphore total) par oxydation quantitative produisant une solution aqueuse d�orthophosphate qu�il convient d�analyser
pour déterminer la teneur en phosphate conformément à la méthode donnée dans l�EN ISO 6878, l�EN ISO 10304-2, ou
selon toute méthode validée équivalente.
Le domaine de mesurage de la méthode a pour limite maximale 50 g/kg P en partant du principe que la
dilution du produit minéralisé est appropriée pour la phase finale de mesurage.
