Non Equilibrium Thermodynamic Studies Through Activation Parameters In Transport Phenomenon Across Ion Exchange Membranes

Transport phenomenon across membranes are very important as they work as guiding principles for drug permeation studies across biological membranes. Classical thermodynamics is confined to the systems of equilibrium i.e. to reversible processes only and cannot be applied to the irreversible systems where variables defining the systems are changing with time and situation. The utility of irreversible thermodynamics lies in the evaluation of entropy production by use of the equation for conservation of mass energy and Gibb’sequation.. In the present investigation membrane is prepared by mechanical compression of cation exchange resin Indion 236 with adhesive araldite and has been characterized in terms of membrane constant A/l.Filteration CoefficientLP for different concentrations of aqueous solutions of glucose and sucrose at different temperatures have been determined. The present study tries to calculate values of Gibb’s free energy , entropy and enthalpy for transport across ion exchange membrane using values of filteration coefficient LP equivalent pore radius , concentration of solutes and temperature of study..
