Abstract: The effect of external and internal diffusion on the rate of adsorption of CS₂ on the active carbon 'Supersorbon' was studied. For the evaluation, kinetic equations of the external diffusion, derived from the area of validity of the Freundlich and Langmuir equations of the adsorption isotherm, were applied. In the area of linear speeds of the mixt. of CS₂ with air and in the area of the concns. suitable for practical use, the rate of adsorption is affected not only by the external but also by the internal diffusion. Three new kinetic equations with the limitation of their validity are given.
