The adsorption equilibria and adsorption rates of fructose and of glucose on aqueous suspensions of fullers earth were determined at various temperatures. The Langmuir adsorption equations were fitted to the equilibrium data and the Langmuir constants were determined so that isotherms could be developed for any pair of parametric pumping operating temperatures.
This glucose+fructose+water system was then subjected to continuous thermal parametric pumping for the separation of glucose and fructose. The operating conditions required for the separation were determined from the experimental adsorption rates and equilibrium isotherms. Samples taken from the continuous top and bottom streams were analyzed by polarimetry for fructose content and by evaporation for total sugar concentration. The results compared favourably with those predicted by the equations of Chen and Hill(1). Although the separation was successful,the cycle times required were very long due to the time required to reach adsorption equilibrium.
