茨威特所提出的色层分离法包含多种类型:吸附的,沉淀的,分布的和离子交换的色层分离法。近年来在分析化学的实践中,这类方法很广泛地被采用着。对于阳离子的分析,应用离子交换的色层分离法,是有效果的。在分析化学中,这种方法虽然不能认为是独立的,但它对于复杂物质的分析却是非常重要的一个中间步骤。藉助于离子的交换作用,可以将混合物的各 The color separation method proposed by Cvett contains many types: adsorption, sedimentation, distribution and ion exchange chromatography. In recent years in the practice of analytical chemistry, such methods are widely used. For cation analysis, the use of ion-exchange chromatography is effective. In analytical chemistry, although this method can not be considered as independent, its analysis of complex matter is an important intermediate step. With the exchange of ions, the mixture can be made individually
