Abstract: From an analysis of the kinetic isotherms of adsorption of organic sub­stances on activated carbon Supersorbon measured in the temperature interval between melting point and boiling point it follows that the half-time of the process depends neither on temperature nor on the size of grains. The half-time was determined from the whole kinetic isotherm on the basis of the Trapnell equation and was found to be in a good agreement with the experimental value resulting from the kinetic isotherm. From the confrontation of activation energy with isosteric heat it may be conclu­ded that the surface diffusion characterized by the activation energy equal to a half of isosteric heat can manifest itself at higher values of adsorption.
