[New method of derivation of practical Kedem-Katchalsky membrane transport equations].
In the paper original manier of derivation of practical transport Kedem-Katchalsky equations (K-K) describing fluxes: volume of solute (Jv) and dissolved substance (Js) for nonelectrolyte, evoked by simultaneous action of direct oriented hydrostatic (deltap) and osmotic (deltaII) pressures of nonelectrolytic solutions was presented. Mathematic expressions describing oefficients characterizing permeability of the membrane: omegadeltaII and omegadeltap, manners of their derivationand their physical interpretation were presented. Equation describing coefficient LD was also derived. Suggested manier of derivation makes K-K equations easier to interpret.
