Fertilizers - Determination of water content (Karl Fischer methods) - Part 1: Methanol as extracting medium
This European Standard specifies a Karl Fischer titrimetric method for the determination of the water content of fertilizers based on the use of methanol as extracting medium.
The method is applicable to all solid mineral fertilizers. The result (KFM water) includes "free" water and extracted water of crystallization from the following components of fertilizers: calcium nitrate tetrahydrate (Ca(NO3)2·4H2O); calcium hydrogen phosphate dihydrate (CaHPO4·2H2O); calcium sulfate dihydrate (gypsum, CaSO4·2H2O), calcium sulfate hemihydrate (CaSO4·0,5H2O); magnesium sulfate heptahydrate (MgSO4·7H2O) ; potassium chloride magnesium sulfate water (1/1/2,75, Kainite, KCl·MgSO4·2,75H2O); potassium magnesium sulfate hexahydrate (Schoenite, K2SO4·MgSO4·6H2O); potassium magnesium sulfate tetrahydrate (Leonite, K2SO4·MgSO4·4H2O); potassium sulfate calcium sulfate monohydrate (Syngenite, K2SO4·CaSO4·H2O); potassium chloride magnesium chloride hexahydrate (Carnallite, KCl·MgCl2·6H2O); magnesium nitrate hexahydrate (Mg(NO3)2·6H2O).
Metal oxides and hydroxides soluble in methanol and pyridine will have an effect which can be corrected for, if their content is known.
Düngemittel - Bestimmung des Wassergehaltes (Karl-Fischer-Verfahren) - Teil 1: Methanol als Extraktionsmittel
Diese Europäische Norm legt ein titrimetrisches Karl-Fischer-Verfahren für die maßanalytische Bestimmung des Wasser-gehaltes von Düngemitteln fest, das auf der Verwendung von Methanol als Extraktionsmittel basiert.
Das Verfahren gilt für alle festen mineralischen Düngemittel. Das Ergebnis (KFM-Wasser) umfasst ¿freies" Wasser sowie extrahiertes Kristallwasser der folgenden Düngemittelbestandteile: Calciumnitrattetrahydrat (Ca(NO3)2 · 4H2O); Calciumhydrogenphosphatdihydrat (CaHPO4 · 2H2O); Calciumsulfatdihydrat (Gips, CaSO4 · 2H2O), Calciumsulfa-themihy-drat (CaSO4 · 0,5H2O); Magnesiumsulfatheptahydrat (MgSO4 · 7H2O); Kaliumchlorid-Magnesiumsulfathydrat-wasser (1/1/2,75, Kainit, KCl · MgSO4 · 2,75H2O); Kalium-Magnesium-sulfat-hexahydrat (Schoenit, K2SO4 · MgSO4 · 6H-2O); Kalium-Magnesiumsulfattetrahydrat (Leonit, K2SO4 · MgSO4 · 4H2O); Kaliumsulfat-Calciumsulf-atmonohydrat (Syngenit, K2SO4 · CaSO4 · H2O); Kaliumchlorid-Magnesiumchloridhexahydrat (Carnallit, KCl · MgCl2 · 6H2O); Magnesiumnitrathexahy-drat (Mg(NO3)2 · 6H2O).
In Methanol und Pyridin lösliche Metalloxide und Hydroxide haben Auswirkungen, die jedoch korrigiert werden können, falls deren Anteil bekannt ist.
Engrais - Détermination de la teneur en eau (Méthodes Karl Fischer) - Partie 1: Le méthanol comme milieu d'extraction
La présente norme spécifie une méthode Karl Fischer de titrage de la teneur en eau des engrais, reposant sur l'utilisation de méthanol comme milieu d'extraction.
La méthode est applicable à toutes les engrais solides. Le résultat (eau KFM) englobe l'eau "libre" et l'eau de cristallisation des éléments suivants des matières fertilisantes : nitrate de calcium tétrahydraté (Ca(NO3)2.4H2O), hydrogénophosphate de calcium dihydraté (CaHPO4).2H2O), sulfate de calcium dihydraté (gypse, (CaSO4.2H2O), sulfate de calcium hémihydraté (CaSO4.0,5 H2O), sulfate de magnésium heptahydraté (MgSO4.7H2O), eau au sulfate de magnésium/chlorure de potassium (1°1/2,75, Kainite, KCl MgSO4.2,75H2O), sulfate de magnésium-potassium hexahydraté (Schoenite, K2SO4 MgSO4.6H2O), sulfate de magnésium-potassium tétrahydraté (Léonite, K2SO4 MgSO4 . 4H2O), sulfate de potassium - sulfate de calcium monohydraté (Syngénite, K2SO4 CaSO4.H2O), chlorure de potassium - chlorure de magnésium hexahydraté (carnallite, KCl MgCl2.6H2O), nitrate de magnésium hexahydraté (Mg(NO3)2.6H2O).
Les oxydes et les hydroxydes de métaux solubles dans le méthanol et la pyridine ont un effet qui peut être corrigé si leur teneur est connue.
