Fertilizers and liming materials - 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 and liming materials.
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 1   In case of reducing or oxidizing fertilizer matrix, no valid Cr(VI) content can be reported.
NOTE 2   The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated.

Düngemittel und Kalkdünger - 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 und Kalkdüngern 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 1 " Bei Vorliegen einer reduzierenden oder oxidierenden Düngemittelmatrix kann der Chrom(VI)-Gehalt nicht zuverlässig ermittelt werden.
ANMERKUNG 2 Der Begriff Düngemittel ist durchgängig in dieser Europäischen Norm verwendet worden und schließt, wenn nicht anders angegeben, die Kalkdünger mit ein."

Engrais et amendements minéraux basiques - Dosage du chrome (VI) par spectrophotométrie (méthode A) et chromatographie ionique avec détection spectrophotométrique (méthode B)

La présente Norme européenne spécifie deux méthodes pour la détermination de la teneur en chromate soluble dans les engrais et les amendements minéraux basiques.
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 1   En cas de matrice d'engrais oxydante ou réductrice, aucune teneur en Cr(VI) valide ne peut être énoncée.
NOTE 2   Le terme engrais est utilisé tout au long du corps de la présente Norme européenne et inclut les amendements minéraux basiques sauf indication contraire.

Gnojila in sredstva za apnjenje - 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 in sredstvih za apnjenje.
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.
OPOMBA 1: V primeru zmanjšanja ali oksidacije matrice gnojila ni mogoče poročati o veljavni vsebnosti Cr(VI).
OPOMBA 2: Izraz »gnojilo« se uporablja v celotnem glavnem delu tega evropskega standarda in vključuje sredstva za apnjenje, če ni navedeno drugače.
