TL;DR: In this article, a model for the intradiffusional kinetics of adsorption, taking into account the different mobilities of the molecules adsorbed in micro-, supermicro-, and mesopores and the bonding of such pores in an active carbon particle, was proposed.
Abstract: A model is proposed for the intradiffusional kinetics of adsorption, taking into account the different mobilities of the molecules adsorbed in micro-, supermicro-, and mesopores and the bonding of such pores in an active carbon particle. Within the framework of the model it has been shown that the effective diffusion coefficient of the adsorbed molecules depends on the structural and sorption characteristics of the material and the concentration conditions of the process being carried out. The model has been used to make an analysis of experimental data for adsorption of organic materials dissolved in water by active carbon having nonuniform pores.
