Fertilizers - Determination of trace elements - Determination of chromium(VI) by photometry (method A) and by ion chromatography with spectrophotometric detection (method B)

This European Standard specifies two methods for the determination of the content of soluble chromate in fertilizers.
Method A specifies the determination of chromate after extraction with water by photometry. This method can be used to determine Cr(VI)-mass fractions in solids higher than 1 mg/kg.
Method B specifies the determination of chromate by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE   In case of reducing or oxidizing fertilizer matrix, no valid Cr(VI) content can be reported.

Düngemittel - Bestimmung von Elementspuren - Bestimmung von Chrom(VI) mit Photometrie (Verfahren A) und mit Ionenchromatographie mit spektrometrischer Detektion (Verfahren B)

Diese Europäische Norm legt zwei Verfahren zur Bestimmung des Gehalts an löslichem Chromat in Düngemitteln fest.
Verfahren A legt die Bestimmung von Chromat nach Extraktion mit Wasser durch Photometrie fest. Dieses Verfahren ist anwendbar für die Bestimmung von Chrom(VI)-Massenanteilen von mehr als 1 mg/kg in Feststoffen.
Verfahren B legt die Bestimmung von Chromat durch alkalischen Aufschluss und Ionenchromatographie mit spektrometrischer Detektion fest. Dieses Verfahren ist anwendbar für die Bestimmung von Chrom(VI)-Massenanteilen von mehr als 0,1 mg/kg in Feststoffen.
ANMERKUNG   Bei Vorliegen einer reduzierenden oder oxidierenden Düngemittelmatrix kann der Chrom(VI)-Gehalt nicht zuverlässig ermittelt werden.

Engrais - Dosage des éléments traces - Dosage du chrome (VI) par spectrophotométrie (méthode A) et chromatographie ionique avec détection spectrophotométrique (méthode B)

Cette norme européenne spécifie deux méthodes de détermination de la teneur en chromate soluble dans les engrais.
La méthode A présente la détermination du chromate après extraction avec de l’eau par spectrophotométrie. Cette méthode peut être utilisée afin de déterminer les fractions massiques de Cr(VI) supérieures à 1 mg/kg dans les solides.
La méthode B présente la détermination du chromate par digestion alcaline et chromatographie ionique avec détection spectrophotométrique. Cette méthode peut être utilisée afin de déterminer les fractions massiques de Cr(VI) supérieures à 0,1 mg/kg dans les solides.
NOTE   En cas de matrice d’engrais oxydante ou réductrice, aucune teneur en Cr(VI) valide ne peut être énoncée.

Gnojila - Določevanje elementov v sledovih - Določevanje kroma (VI) s fotometrijo (metoda A) in z ionsko kromatografijo s spektrofotometrijsko detekcijo (metoda B)

Ta evropski standard določa dve metodi za določevanje vsebnosti topnega kromata v gnojilih. Metoda A določa določevanje kromata po vodni ekstrakciji s fotometrijo. Ta metoda se lahko uporablja za določevanje masnih deležev Cr(VI), višjih od 1 mg/kg, v trdnih snoveh. Metoda B določa določevanje kromata z alkalnim razklopom in ionsko kromatografijo s spektrofotometrijsko detekcijo. Ta metoda se lahko uporablja za določevanje masnih deležev Cr(VI), višjih od 0,1 mg/kg, v trdnih snoveh.
