title: [Estimation method of the concentration boundary layers thicknesses in a single-membrane system containing binary solutions].
abstract: On a basis of the Kedem-Katchalsky formalism, the estimation method of the concentration boundary layers thicknesses (delta) in a single-membrane system containing binary solutions was devised. Mathematical formula, which is a basis of this method, contains transport membrane (L(p), sigma, omega) and solution (D, C) parameters and volume osmotic flux (J(v)). These values can be determined in a series of independent experiments. Calculated values (delta) are nonlinearly dependent on concentrations of investigated solutions and membrane system configuration. These nonlinearities are an effect of a competition between spontaneously occurring diffusion and convection processes.
