Fertilizers - Determination of chelating agents in fertilizers by chromatography - Part 1: Determination of EDTA, HEEDTA and DTPA by ion chromatography

This European Standard specifies a method for the chromatographic determination of the total amount of each of the individual chelating agents EDTA, HEEDTA, and DTPA in fertilizers containing one or more of these substances. The method allows the identification and the determination of the total water soluble fraction of each of these chelating agents. It does not allow to distinguish between the free form and the metal bound form of the chelating agents.
NOTE   EDTA, HEEDTA and DTPA are abbreviations used in this European Standard for the sake of simplicity. For complete names see Annex A.
This method applies to fertilizers containing chelates of one or more of the following micro-nutrients: cobalt, copper, iron, manganese, zinc and with a mass fraction of at least 0,1 %.

Düngemittel - Bestimmung von Chelatbildnern in Düngemitteln mit Chromatographie - Teil 1: Bestimmung von EDTA, HEEDTA und DTPA mit Ionenchromatographie

Diese Europäische Norm legt ein Verfahren zur chromatographischen Bestimmung des Gesamtgehalts von jedem einzelnen der Chelatbildner EDTA, HEEDTA und DTPA in Düngemitteln fest, die eine oder mehrere dieser Substanzen enthalten. Das Verfahren ermöglicht die Identifizierung und Bestimmung des Gesamtanteils an wasserlöslichen Bestandteilen jedes dieser Chelatbildner. Es erlaubt keine Unterscheidung zwischen der freien Form und der metallisch gebundenen Form der Chelatbildner.
ANMERKUNG EDTA, HEEDTA und DTPA sind Abkürzungen, die in dieser Europäischen Norm der Einfachheit halber verwendet werden. Bezüglich der vollständigen Bezeichnungen siehe Anhang A.
Dieses Verfahren gilt für Düngemittel, die Chelate von einem oder mehreren der folgenden Spurennährstoffe enthalten: Kobalt, Kupfer, Eisen, Mangan, Zink mit einem Massenanteil von mindestens 0,1 %.

Engrais - Détermination des agents chélatants dans les engrais par chromatographie - Partie 1: Détermination du EDTA, HEEDTA et DTPA par chromatographie ionique

La présente norme européenne spécifie une méthode pour la détermination par chromatographie de la quantité totale de chacun des agents chélatants individuels EDTA, HEEDTA et DTPA dans les engrais contenant une ou plusieurs de ces substances. La méthode permet d’identifier et de déterminer la proportion totale soluble dans l’eau de chacun de ces agents chélatants. Elle ne permet pas de faire la distinction entre la forme libre et la forme métallique de l’agent chélatant.
NOTE   EDTA, HEEDTA et DTPA sont des abréviations employées dans la présente norme européenne dans un souci de simplicité : pour les noms complets, se reporter à l’annexe A.
La présente méthode s’applique aux engrais contenant des chélates d’au moins un des oligo-éléments suivants : cobalt, cuivre, fer, manganèse, zinc, avec une fraction massique d’au moins 0,1 %.

Any anion exchange column with comparable capacity, hydrophobicity, and selectivity can probably be used. NOTE 2 Columns can, in their native state, exhibit some sensitivity towards various anions (e.g. nitrate, sulfate, phosphate) which can disappear after treatment with excess iron. It can be necessary to precondition the column prior to its use by repeated injections, at least 10, of the iron(III) solution (6.9), followed by equilibration under eluent flow for at lea
