For a mathematical model that incorporates internal-diffusion kinetics and sorbent swelling, we consider the inverse problem of determining the sorption isotherm and the porosity coefficient from two output dynamic curves. A gradient-type iterative method utilizing the conjugate problem technique is proposed and results of numerical experiments are reported. The results are used to investigate the features of the proposed method.
