Comments on a general theory of ion-exchange chromatographic separation processes

摘要

In this paper, a theory presented by Kakihana and Oi is discussed and the mistakes made in their theoretical development are pointed out. From the discussion, it is concluded that application of this theory to experiments will need further consideration. As an important separation technology, ion-exchange chromatography has been widely applied to the separation of various kinds of mixtures. Theoretical treatment of chromatographic processes is an old and a complex problem. There are a large number oftheories that differ from each other in their assumptions and their degree of complexity [1,2]. In a series of papers [3-8], Kakihana and Oi presented a theory for chromatographic separation processes and applied it to experiments.
