Fertilizers - Determination of molybdenum in concentrations > 10 % using a gravimetric method with 8-hydroxyquinoline

This Technical Specification specifies the procedure for determination of total and water extractable molybdenum in mineral fertilizers containing more than 10 % molybdenum. This method is applicable to water and aqua regia fertilizer extracts obtained according to EN 260172 and/or EN 260176.

Düngemittel - Bestimmung von Molybdän in Konzentrationen > 10 % durch Gravimetrie mit 8-Hydroxychinolin

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung von Gesamt-Molybdän und wasserextrahierbarem Molybdän in mineralischen Düngemitteln, die mehr als 10 % Molybdän enthalten, fest.
Dieses Verfahren ist auf Wasser- und Königswasser-Extrakte von Düngemitteln anwendbar, die nach prEN 16962:2016 und/oder prEN 16964:2016 erhalten wurden.

Engrais - Dosage du molybdène dans des concentrations > 10 % en utilisant une méthode gravimétrique à la 8-hydroxyquinoléine

La présente Spécification technique spécifie une méthode pour le dosage du molybdène total et du molybdène extractible à l’eau dans des engrais minéraux contenant plus de 10 % de molybdène.
Cette méthode est applicable aux extraits d’engrais aqueux et à l’eau régale obtenus conformément au prEN 16962:2016 et/ou au prEN 16964:2016.

Gnojila - Določevanje molibdena v koncentracijah do 10 % z gravimetrično metodo z 8-hidroksikinolinom

Ta tehnična specifikacija določa postopek za določevanje skupne vsebnosti molibdena in molibdena, ki ga je mogoče ekstrahirati z vodo, v mineralnih gnojilih, ki vsebujejo več kot 10 % molibdena. Ta metoda se uporablja za ekstrakte gnojil v vodi in zlatotopki, pridobljene v skladu s standardom EN 260172 in/ali EN 260176.
