Modeling of NaF in (glucose/sucrose + water) Mixture; Binary and Ternary Mixing Ion-Nonelectrolyte Interaction Parameters

The determination of the thermodynamic properties of electrolytes in aqueous and in mixedsolutions is necessary for understanding the nature of various ionic interactions and also forhandling of various industrial and environmental processes. Within multicomponent systemsthose of the (electrolyte+ sugar + water) type are especially important for understanding thebehaviour of sugars in living organisms[1].the experimental data for this system obtained fromemf measurements of the electrochemical cell containing two ion selective electrodes. In thissystem to investigate the effect of ion−nonelectrolyte interactions the modified Pitzer equationswere used for the determination of the binary and ternary ion−nonelectrolyte interactionparameters[2]. In (...) Using this model, ion-solvent interaction parameters were calculated for the mentionedsystems. For example, χ(1,0)AMX was calculated for the NaF electrolyte system in mixed solvent(sugar + water), which has negative values indicating the ion accumulation in the solvent.
