标准摘要
[中文适用范围]： 本标准规定了以氯化六氨钴(III)溶液为萃取剂测定土壤中阳离子交换容量(CEC)和可交换阳离子(Al、Ca、Fe、K、Mg、Mn、Na)含量的方法。 对于含有碳酸钙的土壤，方解石饱和六氨合氯化钴 (III) 溶液专门用于测定可交换的 Ca。 本文件适用于根据 ISO 11464 制备的所有类型的风干土壤样品。 [外文原描述]： 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.
