Water quality - Determination of six complexing agents - Gas-chromatographic method (ISO 16588:2002)

This International Standard specifies a method for the determination of the following six water-soluble organic complexing agents in the concentration range from 0,5 micrograms/litre to 200 micrograms/litre:
EDTA (ethylenedinitrilotetraacetic acid);NTA (nitrilotriacetic acid);DTPA (diethylenetrinitrilopentaacetic acid);MGDA (methylglycinediacetic acid);ß-ADA (ß-alaninediacetic acid);1,3-PDTA (1,3-propylenedinitrilotetraacetic acid).
The method is applicable to drinking, ground, surface and waste water.

Wasserbeschaffenheit - Bestimmung von sechs Komplexbildnern - Gaschromatographisches Verfahren (ISO 16588:2002)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der in der Tabelle 1 genannten löslichen organischen Komplexbildner fest. Das Verfahren ist geeignet für einen Konzentrationsbereich von 0,5 µg/l bis 200 µg/l und einem Probenvolumen zwischen 50 ml und 100 ml. Bei Verdünnung ändert sich der Konzentrationsbereich. Das Verfahren ist anwendbar auf Trinkwasser, Grund-, Oberflächen- und Abwasser.
Tabelle 1 - Nach diesem Verfahren bestimmbare Komplexbildner
Nr   Name   Zusammensetzung   Molare Masse g/mol   CAS-Nr a  
1   EDTA - Ethylendinitrilotetraessigsäure   C10H16O8N2   292,25   60-00-4
2   NTA - Nitrilotriessigsäure   C6H9O6N   191,14   139-13-9
3   DTPA - Diethylentrinitrilopentaessigsäure   C14H23O10N3   393,35   67-43-6
4   MGDA - Methylenglycindiessigsäure   C7H11O6N   205,17   29578-05-0
5   ß-ADA - ß-Alanindiessigsäure   C7H11O6N   205,17   6245-75-6
6   1,3-PDTA - 1,3-Propylendinitrilotetraessigsäure   C11H18O8N2   306,27   1939-36-2
a   CAS: Chemical Abstracts System
Für Abwasser ist zur Verminderung von Matrixeinflüssen ein geringeres Probenvolumen, z. B. 5 ml oder 10 ml, vorteilhaft.
Die Adsorption der sechs Komplexbildner an Feststoffe ist vernachlässigbar klein.
Nach diesem Verfahren sind auch weiteres Komplexbildner ähnlicher Zusammensetzung bestimmbar, vorausgesetzt, sie verhalten sich bei der Probenvorbereitung, Derivatisierung und Gaschromatographie gleichartig. Dies muss im Einzelfall geprüft werden.

Qualité de l'eau - Dosage des agents complexants - Méthode par chromatographie en phase gazeuse (ISO 16588:2002)

L'ISO 16588:2002 spécifie une méthode pour le dosage de six agents complexants organiques solubles dans l'eau, dans la gamme de concentrations allant de 0,5 microgrammes/litre à 200 microgrammes/litre. Ces six agents complexants sont les suivants:
EDTA (acide éthylènedinitrilotétraacétique);NTA (acide nitrilotriacétique);DTPA (acide diéthylènetrinitrilopentaacétique);MGDA (acide méthylglycinediacétique);bêta-ADA (acide bêta-alaninediacétique);1,3-PDTA (acide 1,3-propylènedinitrilotétraacétique).
La méthode est applicable à l'eau potable, aux eaux souterraines, aux eaux de surface et aux eaux usées.
