Abstract
The resistance of the intraparticle diffusion of different pollutants into CNTs is considered the main challenge in the wastewater treatment. Hence in this investigation, we discuss the kinetic parameters affecting the diffusion of different pollutants from municipal wastewater into the carbon nanotubes (CNTs) matrix. Different models (Pseudo first order, Pseudo second order, intraparticle diffusion, Avrami and mixed first and second order models) were studied to describe the adsorption characteristics of the reduction in chemical and biochemical oxygen demand of municipal wastewater in addition to the kinetic profile of some nutrients and heavy metals ions in the existence of CNTs. Finally, the mechanism of sorption of these main pollutants was proposed.Keywords
