Approximate matrix methods for multicomponent mass transport in membranes
Abstract
Several investigators have suggested models for multicomponent mass transfer in membranes and other condensed systems. The forces are given as linear functions of the fluxes in these models, and thus flux expressions are found by inversion. In carrying out this inversion, certain constants that must be determined by experiment become enmeshed in complicated functions involving the concentrations. Here, the inversion process is carried out by an approximate method, and the conditions for convergence are given. Methods are suggested for determining the required constants from experimental data.
