Developing Kedem-Katchalsky equations of the transmembrane transport for binary nonhomogeneous non-electrolyte solutions.
The paper presents developing Kedem-Katchalsky equations for binary non-homogeneous non-electrolyte solutions. The obtained equation describes the volume flux (Jv) depending on parameters of a membrane (reflection, a, hydraulic permeability, Lp, and solute permeability, omega coefficients), solution parameters (concentration, Ck, density, rho, kinematic viscosity, v and diffusion coefficient, D) and concentration Rayleigh number (Rc). In order to verify of the elaborated equation of Jv for the single-membrane system, there were made the calculations of the dependence: Jv = f(deltaC)(R(C),zeta s = const) Jv = f(R(C))(deltaC, zetta s = const), and Jv = f(zetaS)(R(C),deltaC = const), for aqueous glucose solutions and the membrane made of bacterial cellulose.
