The distribution coefficient (Kd) of Cs on ferrierite decreased with increasing concentration of the coexisting inorganic cations in the order of Na+>H+>K+>NH4+. A linear relationship with a slope of about -1 was obtained between log Kd and log[M+] above 0.1M (=mol/dm3). The retention volume (VR) of Cs in chromatography also decreased in a similar manner to Kd, depending on the kind of inorganic cations. The VR value can be predicted from the Kd value based on the linear relation. The column efficiency was improved with fine particles of ferrierite, yielding the elution percentage above 95%.
