Frictional coefficient-11 (evaluation of degree of coupling,efficiency of energy conversion and membrane parameters)

Summary Frictional coefficients between membrane matrix and permeants have been evaluated for ThO₂/DMF system. The degrees of coupling q and the maximum value of the efficiencies of electrokinetic energy conversion, _max, for both the modes of conversion, viz., electro-osmotic flow and streaming potential have been calculated from these coefficients and the results have been found to be in accordance with non-equilibrium thermodynamic theories. The values of frictional coefficients have also been used for characterising the membrane, viz., in determining the equivalent pore radii and the number of pores.With 2 tables
