文摘

Binary mutual diffusion coefficients measured by the Taylor dispersion method in two different laboratories(University of Naples, Federico II, Italy, and University of Coimbra, Portugal) are reported for aqueous solutionsof lactose, sucrose, glucose, and fructose at various concentrations (0.001 to 0.1) mol·dm^-3 and temperatures(298.15 to 328.15) K. The hydrodynamic radius and activation energy for the diffusion of aqueous sugars arecalculated from those results. In addition, the measured diffusion coefficients are used with the Hartley equationto estimate activity coefficients for aqueous lactose, sucrose, glucose, and fructose.
