Hybrid Version of the Kedem-Katchalsky-Peusner Equations for Diffusive and Electrical Transport Processes in Membrane.

One of the most important formalisms used to describe membrane transport is Onsager-Peusner thermodynamics (TOP). Within the TOP framework, a procedure has been developed for the transformation of the Kedem-Katchalsky (K-K) equations for the transport of binary electrolytic solutions across a membrane into the Kedem-Katchalsky-Peusner (K-K-P) equations. The membrane system with an Ultra Flo 145 Dialyser membrane used for hemodialysis and aqueous NaCl solutions was used as experimental setup.

Network Derivation of Liquid Junction Potentials in Single-Membrane System.

Peusner's network thermodynamics (PNT) is one of the more important formalisms of nonequilibrium thermodynamics used to describe membrane transport and the conversion of the internal energy of the system into energy dissipated in the environment and free energy used for the work involved in the transport of solution components in membrane processes. A procedure of transformation the Kedem-Katchalsky (K-K) equations for the transport of binary electrolytic solutions through a membrane to the Kedem-Katchalsky-Peusner (K-K-P) equations based on the PNT formalism for liquid junction potentials was developed. The subject of the study was a membrane used for hemodialysis (Ultra Flo 145 Dialyser) and aqueous NaCl solutions.
