Fertilizers and liming materials - Determination of cadmium, chromium, lead and nickel by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution

This European Standard specifies a method for the determination of the content of cadmium, chromium, nickel and lead in fertilizers with inductively coupled plasma atomic emission spectrometry (ICP-AES) after extraction with aqua regia. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Ni and Pb.
NOTE   Due to significant interference from Cu, Fe and Mn, no valid results can be reported using this method for fertilizer matrices containing high concentrations (>/= 10 %) of these micro-nutrients.

Düngemittel und Kalkdünger - Bestimmung von Cadmium, Chrom, Blei und Nickel mit Atomemissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-AES) nach Königswasseraufschluss

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Gehalts an Cadmium, Chrom, Nickel und Blei in Düngemitteln mit Atomemissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-AES) nach Königswasseraufschluss fest. Die Bestimmungsgrenzen sind sowohl von der Probenmatrix als auch vom verwendeten Gerät abhängig, werden jedoch etwa bei 0,3 mg/kg für Cd und 1 mg/kg für Cr, Ni und Pb erwartet.
ANMERKUNG   Aufgrund signifikanter Störungen durch Cu, Fe und Mn können bei Anwendung dieses Verfahrens für Düngemittelmatrizes mit hohen Konzentrationen (≥ 10 %) dieser Spurennährstoffe keine zuverlässigen Ergebnisse ausgewiesen werden.

Engrais et amendements minéraux basiques - Détermination du cadmium, chrome, plomb et nickel par spectrométrie d'émission atomique avec plasma induit par haute fréquence (ICP-AES) après digestion à l'eau régale

La présente norme européenne spécifie une méthode permettant de déterminer la teneur en cadmium, chrome, nickel et plomb dans les engrais par spectrométrie d’émission atomique avec plasma à couplage inductif (ICP-AES) après extraction à l’eau régale. Les limites de quantification dépendent de la matrice de l’échantillon ainsi que de l’instrument, mais peuvent être attendues de l’ordre de 0,3 mg/kg pour Cd et 1 mg/kg pour Cr, Ni et Pb.
NOTE Du fait d’une interférence significative du Cu, Fe et Mn, aucun résultat valide ne peut être donné en utilisant cette méthode pour les matrices engrais contenants des concentrations élevés (≥ 10%) en ces oligo-éléments.

Gnojila in sredstva za apnjenje - Določevanje kadmija, kroma, svinca in niklja z atomsko emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP/AES) po raztapljanju v zlatotopki (vključno z dopolnilom A1)

Ta evropski standard določa metodo za določevanje vsebnosti kadmija, kroma, niklja in svinca v gnojilih z atomsko emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP-AES) po ekstrakciji z zlatotopko. Meje kvantifikacije so odvisne od matrice vzorca in instrumenta, vendar za Cd običajno znašajo približno 0,3 mg/kg, za Cr, Ni in Pb pa 1 mg/kg.
OPOMBA: Zaradi znatne interference primesi Cu, Fe in Mn ni mogoče posredovati nobenih veljavnih rezultatov s to metodo za matrice gnojil, ki vsebujejo visoke koncentracije teh mikro hranil (>/= 10 %).

1,18 g/ml. 6.3 Nitric acid, c(HNO3) = 16 mol/l; not less than 65 % volume fraction;
1,42 g/ml. 6.4 Mixed solution of 0,8 mol/l nitric acid and 1,8 mol/l hydrochloric acid. Mix 150 ml of hydrochloric acid (6.2) and 50 ml nitric acid (6.3) to 1,0 l of water (6.1). 6.5 Standard stock solutions, cadmium, chromium, nickel and lead standard stock solutions, e.g.
= 1 000 mg/l for each element. Use suitable stock solutions. Both single-element stock solutions and multi-element stock solutions with adequate specification stating the acid used and the preparation technique are commercially available. It is recommended to use commercially available standard stock solutions for cadmium, chromium, nickel and lead. 6.6 Working standard solutions. Depending on the scope, different working standard solutions may be necessary. In general, when combining elements in working standard solutions, their chemical compatibility shall be regarded. Spectral interferences from other elements present in working standard solutions also need to be considered. Various combinations of elements at different concentrations may be used, provided that the standard stock solutions (6.5) are diluted with the same acid and in equal concentration as the acid in the test solution. NOTE In equal concentrations (in mg/l), cadmium, chromium, nickel and lead are compatible in a multi-element standard solution for the determination by ICP-AES for this application. 6.6.1 Working standard solution I,
= 100 mg/l for cadmium, chromium, nickel and lead. Dilute 10,0 ml of each standard stock solution of cadmium, chromium, nickel and lead (6.5) to 100,0 ml with the mixed acid solution (6.4) in the same 100 ml flask. If non-equal concentrations of cadmium, chromium, nickel and lead are needed, dilute the required volumes into 100,0 ml. This solution is used to prepare spiked test solutions and standard and calibration solutions. 6.6.2 Working standard solution II,
= 10 mg/l for cadmium, chromium, nickel and lead. Dilute 10,0 ml of the working standard solution I of cadmium, chromium, nickel and lead (6.6.1) to 100,0 ml with the mixed acid solution (6.4) in a 100 ml flask. If non-equal concentra
