摘要：
The ionic mean activity coefficients of NaBr in trehalose-water and cellobiose-water mixtures have been experimentally determined at 298.15 K from electrochemical potential measurements by an electrochemical cell containing two ion selective electrodes (ISE), together with the activity coefficients of the disaccharides. The parameters C-1 representing the pair interactions between the disaccharides and NaBr have been obtained. The interactions of NaBr with trehalose, cellobiose and glucose were compared and discussed in terms of their difference in the stereo-structures.
