The apparent distribution coefficients Kapp of glucose, galactose, mannose and fructose onto the resins with different divinylbenzene contents in Li+ , Na+ K+ Ca**2+ and Sr**2+ forms were determined in a dilute system by the moment analysis of the elution profile. The binding constant B of a solute to a counter-ion, which was free from the effect of swelling pressure of the resin, was estimated from the Kapp values based on our previous model where glucose was assumed to form no complex with any counter-ion. The B value for each solute, except for glucose, could be correlated with the dynamic hydration number of the counter-ion.
