適用范圍：This International Standard 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 ahexamminecobalt trichloride solution as extractant.NOTE As the pH of a soil suspension in the hexamminecobalt trichloride solution is close to the pH of the suspensionin water, this method is considered to give the effective CEC, i.e. the CEC at the soil pH.This International Standard is applicable to all types of air-dried soil samples which have been prepared inaccordance with ISO 11464.References and results of the comparison with other methods (barium chloride, ammonium acetate) are givenin Annex A.
