概要

• 論文の詳細を見る

• Binding of 1-decylpyridinium bromide onto poly(vinyl sulfate) in aqueous solution is measured by using a potentiometric titration method which employs propionyl-α-cyclodextrin as a neutral carrier in a 1-decylpyridinium selective electrode. Binding is highly cooperative and biphasic. The first step binding is reduced, while the second one increased on increasing added NaBr concentration. Temperaure dependence is very small giving an enthalpy of binding equal to −1.4 kJ mol<SUP>−1</SUP>.
