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

PUBLISH DATE 2018
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.
