    Abstract - (Show below) - (Hide below)

    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.
