Abstract
Nonstationary diffusion through multilayer membranes has been studied using network thermodynamics together with the electrical circuit simulation routine, SPICE. A network model for a system made up of a multilayer membrane between two external phases is proposed. The concentration profiles in the composite membrane and the decay of the osmotic pressure across various associations (bi- and multilayer) of individual membranes connected in series has been simulated and calculated, thus doing away with the need for highly complex mathematical resolutions of the differential diffusion equations. The effect that a rearrangement of the spatial order of these membranes has on both the osmotic pressure and the activity profile is commented upon.
