Soil quality - Determination of effective cation exchange capacity (CEC) and exchangeable cations using a hexamminecobalt trichloride solution (ISO 23470:2018)

This document specifies a method for the determination of cation exchange capacity (CEC) and the content of exchangeable cations (Al, Ca, Fe, K, Mg Mn, Na) in soils using a hexamminecobalt(III)chloride solution as extractant. For soils containing calcium carbonate a calcite saturated hexamminecobalt(III)chloride solution is specified particularly for determination of exchangeable Ca. This document is applicable to all types of air-dry soil samples which have been prepared according to ISO 11464.

Bodenbeschaffenheit - Bestimmung der effektiven Kationenaustauschkapazität (KAK) und der austauschbaren Kationen mit Hexammincobalt(III)chlorid-Lösung (ISO 23470:2018)

Dieses Dokument legt ein Verfahren zur Bestimmung der Kationenaustauschkapazität (KAK) und des Gehaltes an austauschbaren Kationen (Al, Ca, Fe, K, Mg, Mn, Na) in Böden unter Verwendung einer Hexammincobalt(III)chlorid-Lösung als Extraktionsmittel fest. Bei Böden, die Calciumcarbonat enthalten, ist eine calcitgesättigte Hexammincobalt(III)chlorid-Lösung besonders für die Bestimmung des austauschbaren Ca angegeben. Dieses Dokument gilt für alle Arten von lufttrockenen Bodenproben, die nach ISO 11464 vorbereitet wurden.

Qualité du sol - Détermination de la capacité d'échange cationique (CEC) effective et des cations échangeables à l'aide d'une solution de trichlorure de cobaltihexammine (ISO 23470:2018)

Le présent document spécifie une méthode de détermination de la capacité d'échange cationique (CEC) et de la teneur en cations échangeables (Al, Ca, Fe, K, Mg, Mn, Na) dans le sol à l'aide d'une solution de trichlorure de cobaltihexammine utilisée comme réactif d'extraction. Pour les sols contenant du carbonate de calcium, une solution de trichlorure de cobaltihexammine saturée en calcite est spécifiée, en particulier pour la détermination du Ca échangeable. Le présent document est applicable à tous les types d'échantillons de sol séchés à l'air qui ont été préparés conformément à l'ISO 11464.

Kakovost tal - Določevanje efektivne kationske izmenjalne kapacitete in izmenljivih kationov z uporabo raztopine heksaminokobaltovega triklorida (ISO 23470:2018)

Ta dokument določa metodo za določevanje kationske izmenjalne kapacitete (CEC) in vsebnost izmenljivih kationov (Al, Ca, Fe, K, Mg Mn, Na) v tleh z uporabo raztopine heksaminokobaltovega (III) klorida kot ekstraktanta. Za tla, ki vsebujejo kalcijev karbonat, je kalcitna nasičena raztopina heksaminokobaltovega (III) klorida določena posebej za določevanje izmenljivega kalcija. Ta dokument se uporablja za vse vrste vzorcev tal, posušene na zraku, ki so bili pripravljeni v skladu s standardom ISO 11464.
