DERIVATION OF PRACTICAL KEDEM - KATCHALSKY EQUATIONS FOR MEMBRANE SUBSTANCE TRANSPORT

Abstract

The following paper includes a derivation of practical KedemKatchalsky (K-K) equations for the volume flow J and the solute flow Js for non-electrolytes. This derivation makes the equations clearer and consequently their interpretation also becomes easier. The equations have been derived on the basis of the analysis of the membrane transport generated by simultaneous action of two thermodynamic stimuli: the hydrostatic
