Inorganic micronutrient fertilizers - Determination of the chelated micronutrient content and the chelated fraction of micronutrients - Part 1: Treatment with a cation exchange resin

This document specifies a method for the determination of the chelated iron content and the chelated fraction of iron, in UVCB chelats, EDDHA, EDDHMA, HBED, EDDHSA, in inorganic micronutrient fertilizers by the treatment with a cation exchange resin.
The limit of determination of the chelated iron content highly depends on the specific electrical conductivity of the sample, on the amount of nutrient present, and varies between 0,005 % in simple matrices with high amounts of micronutrient and 0,5 % in more complex cases (see 9.1).

Anorganische Spurennährstoff-Düngemittel - Bestimmung des Gehaltes an chelatisierten Spurennährstoffen und des chelatisierten Anteils an Spurennährstoffen - Teil 1: Behandlung mit einem Kationenaustauscherharz

Dieses Dokument legt ein Verfahren zur Bestimmung des Gehalts an chelatisiertem Eisen sowie des chelatisierten Anteils an Eisen in UVCB-Chelaten, EDDHA, EDDHMA, HBED und EDDHSA in anorganischen Spurennährstoff-Düngemitteln durch Behandlung mit einem Kationenaustauschharz fest.
Die Bestimmungsgrenze des Gehalts an chelatisiertem Eisen hängt stark von der spezifischen elektrischen Leitfähigkeit der Probe und der Menge des vorhandenen Nährstoffs ab und variiert zwischen 0,005 % in einfachen Matrices mit großen Mengen an Spurennährstoffen und 0,5 % in komplexeren Fällen (siehe 9.1).

Engrais inorganiques à base d'oligo-éléments - Détermination de la teneur en oligo-éléments chélatés et de la fraction chélatée des oligo-éléments - Partie 1 : Traitement avec une résine échangeuse de cations

Le présent document spécifie une méthode pour la détermination de la teneur en fer chélaté et de la fraction chélatée de fer, dans les chélates UVCB, l’EDDHA, l’EDDHMA, le HBED, l’EDDHSA, dans les engrais inorganiques à base d’oligo-éléments par traitement avec une résine échangeuse de cations.
La limite de détermination de la teneur en fer chélaté dépend en grande partie de la conductivité électrique spécifique de l’échantillon, de la quantité d’élément nutritif présent, et varie entre 0,005 % dans les matrices simples avec de grandes quantités d’oligo-éléments et 0,5 % dans les cas plus complexes (voir 9.1).

Anorganska gnojila z mikrohranili - Določanje vsebnosti kelatiranih mikrohranil in deleža kelatiranih mikrohranil - 1. del: Obdelava s kationsko izmenjevalno smolo

Ta dokument navaja metodo za določanje vsebnosti kelatiranega železa in kelatiranega deleža železa v UVCB, EDDHA, EDDHMA, HBED, EDDHSA v anorganskih gnojilih z mikrohranili na podlagi obdelave s kationsko izmenjevalno smolo.
Meja določanja vsebnosti kelatiranega železa je močno odvisna od specifične električne prevodnosti vzorca, od količine prisotnega hranila in se giblje med 0,005 % v enostavnih matricah z velikimi količinami mikrohranil in 0,5 % v bolj zapletenih primerih (glej točko 9.1).
