Abstract

単一成分系におけるグルコースとフラクトースのLi<SUP>+</SUP>, Na<SUP>+</SUP>, K<SUP>+</SUP>およびCa<SUP>2+</SUP>形陽イオン交換樹脂に対する見掛けの分配係数を25℃ で測定した.各イオン形樹脂に対する両溶質の分配係数はいずれも溶質濃度に依存し,溶質濃度が高いほど分配係数は大きかった.グルコースは対イオンと複合体を形成しないと仮定して,フラクトースと対イオンとの結合定数を推定する方法を提出し,その値を算出した.得られた結合定数のなかでは,Ca<SUP>2+</SUP>に対する値がもっとも大きかった.

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.
