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

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

This edition has been replaced by ISO 23470:2018.

Abstract / scope

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.
