Apparent Distribution Coefficients of Glucose and Fructose to Cation-Exchange Resins in Some Ionic Forms

Abstract

The apparent distribution coefficients of glucose and fructose to cation-exchange resin in lithium, sodium, potassium, or calcium form at 25° were measured at various concentrations in a single component system. Both coefficients in any ionic form depended on their concentrations and became large at higher concentrations. A method to estimate the binding constant of fructose to a counterion was proposed under the assumption of there being no complex formation between glucose and the counterion, and the constant of fructose to each counter-ion was evaluated. The constant for the calcium ion was larger than those for other counter-ions.
