Department of Chemistry, Himachal Pradesh University, Shimla-171 005 Manuscript received 6 January 1992, revised 12 October 1992, accepted 2 December 1992 Hydrodynamic permeabilities of aqueous solutions of glucose, urea and glucose-urea mixtures have been measured across a titanium oxide membrane. The hydrodynamic permeability decreases with increase in concentration of glucose, urea and glucose-urea mixtures at constant urea concentration. Both sides of the membrane have shown equal flows,
