BS EN ISO 23470:2018

This standard BS EN ISO 23470:2018 Soil quality. Determination of effective cation exchange capacity (CEC) and exchangeable cations using a hexamminecobalt trichloride solution is classified in these ICS categories:

• 13.080.20 Physical properties of soils

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.
