Abstract

This study continues an earlier work devoted to simulation of mass transfer in liquid-liquid systems taking into account mass transfer across fractal interfacial structures. Earlier, using methods of nonequilibrium thermodynamics, we obtained an expression for the generalized thermodynamic force taking into account colloidal chemical phenomena in the interfacial region, such as the formation of disperse interfacial layers and films. Here, using a differential equation with a fractional-order derivative, we estimate the diffusion coefficient of the extractable substance in the interfacial film and the porosity of this film, which is its structural characteristic.
