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

ISO 23470:2007 specifies a method for the determination of the cation exchange capacity (CEC) and the content of exchangeable cations (Al3+, Ca2+, Fe2+, K+, Mg2+, Mn2+, Na+) in soils using a hexamminecobalt trichloride solution as extractant.ISO 23470:2007 is applicable to all types of air-dried soil samples which have been prepared in accordance with ISO 11464.

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

Le présent document fixe une méthode de détermination de la capacité d'échange cationique (CEC) et de la teneur en cations échangeables (AI, Ca, Fe, K, Mg, Mn, Na) dans le sol à l'aide d'une solution de trichlorure de cobaltihexammine utilisée comme réactif d'extraction. Il est applicable à tous les types d'échantillons de sol séchés à l'air qui ont été préparés selon l'ISO 11464.

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

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.
