Cilësia e tokës - Përcaktimi i kapacitetit efektiv të jonokëmbimit të kationeve (CEC) dhe kationeve të këmbyeshëm duke përdorur tretësirën e triklorurit të heksaminkobaltit (ISO 23470:2007)

Soil quality - Determination of effective cation exchange capacity (CEC) and exchangeable cations using a hexamminecobalt trichloride solution (ISO 23470:2007)

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.
