Mass Transfer Studies in Sorbing Porous Media I. Analytical Solutions

摘要: An analytical solution is presented for the movement of chemicals through a sorbing porous medium with lateral or intra-aggregate diffusion. The liquid phase in divided into mobile and immobile regions. Diffusional transfer between two regions assumed to be proportional concentration difference liquids. Sorption processes both dynamic stagnant are instantaneous adsorption isotherm linear. model derived here describes extensive tailing observed during flow an unsaturated, aggregated explains often early breakthrough effluent.
