Abstract
A method for overcoming the difficulty of using realistic interface ad sorption kinetics in mass sorption experiments for the estimation of d iffusivities in solids is described in this paper. The method is shown to possess three important advantages: 1) Complex kinetics are allowe d for interface adsorption processes 2) Analytical solutions can be ob tained for arbitrary interface kinetics 3) No additional parameter is introduced in the estimation problem An important special case is work ed out in detail.
