EN ISO 12782-1:2012

Soil quality - Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Part 1: Extraction of amorphous iron oxides and hydroxides with ascorbic acid (ISO 12782-1:2012)

ISO 12782-1:2012 specifies the determination of the content of "reactive" iron in the form of amorphous iron oxides and hydroxides in soil and other materials by extraction with ascorbic acid. Other materials also include waste. The content of "reactive" iron can be used as input in geochemical models to represent the content of amorphous iron (hydr)oxides.

Bodenbeschaffenheit - Parameter zur geochemischen Modellierung der Elution und Speziation von Bestandteilen in Böden und Materialien - Teil 1: Extraktion amorpher Eisenoxide und -hydroxide mittels Ascorbinsäure (ISO 12782-1:2012)

Der vorliegende Teil der ISO 12782 legt die Bestimmung des Gehalts an "reaktivem" Eisen in Form von amorphen Eisenoxiden und Eisenhydroxiden im Boden und in anderen Materialien durch Extraktion mittels Ascorbinsäure fest. Andere Materialien schließen ebenfalls Abfall ein. Der Gehalt an "reaktivem" Eisen kann als Vorgabe in geochemischen Modellen verwendet werden, um den Gehalt an amorphen Eisen(hydr)oxiden darzustellen.
ANMERKUNG   Obwohl die Extraktion mittels Ammoniumoxalat Oxalsäure (ISO 12782-3) im Allgemeinen zur Einschätzung von "reaktivem" Eisen in Form von Eisenoxiden und Eisenhydroxiden verwendet wird, hat der vorliegende Teil der ISO 12782 in Verbindung mit ISO 12782-2 gezeigt, dass sie im Hinblick auf die Extraktion von amorphen und kristallinen Eisen(hydr)oxiden viel spezifischer sind.

Qualité du sol - Paramètres pour la modélisation géochimique de la lixiviation et de la spéciation des constituants des sols et des matériaux - Partie 1: Extraction des oxydes et hydroxydes de fer amorphe à l'acide ascorbique (ISO 12782-1:2012)

L'ISO 12782-1:2012 spécifie la détermination de la teneur en fer «réactif» présent sous forme d'oxydes et d'hydroxydes de fer amorphe dans le sol et autres matériaux par extraction à l'acide ascorbique. Les autres matériaux incluent également les déchets. La teneur en fer «réactif» peut être utilisée comme une donnée d'entrée dans les modèles géochimiques pour représenter la teneur en oxydes et hydroxydes de fer amorphe.

Kakovost tal - Parametri geokemijskega modeliranja izpiranja in speciacija sestavin v tleh in talnih materialih - 1. del: Ekstrakcija amorfnih železovih oksidov in hidroksidov z askorbinsko kislino (ISO 12782-1:2012)

Ta del standarda ISO 12782 se uporablja za določevanje vsebnosti »reaktivnega« železa v obliki amorfnih železovih oksidov in hidroksidov v tleh in talnih materialih z ekstrakcijo z askorbinsko kislino. Med materiale spadajo tudi odpadki, opisani v uvodu. Vsebnost »reaktivnega« železa je mogoče uporabiti kot vnos v geokemijskih modelih, pri čemer predstavlja vsebnost amorfnih železovih (hidr)oksidov.
