Flue gas desulfurization by activated carbon is an environmental-friendly technique used in thermal power plant. The mass transfer process of SO2 about flue gas desulfurization by activated carbon is analyzed, effective mass transfer velocity of SO2 on fixed bed is proposed and mathematics model is established. Internal diffusivity and internal surface availability coefficient of different activated...
Perfluorooctane sulfonate (PFOS) has increasingly attracted global concerns in recent years and has also been proposed as the candidates of persistent organic pollutants due to their world-wide distribution, environmental persistence and bioaccumulation potential. The adsorption mechanism of PFOS from aqueous solutions onto granular activated carbon (GAC) was investigated. The adsorption reaction...
Arundo donax root was used to prepare activated carbon by H3PO4 activation for the removal of methyl violet (MV). The activated carbon has a micro-mesoporous structure with BET surface area 1392 m2/g. Pseudo-second-order model could predict the adsorption kinetics for the entire process. The sorption involved several stages and the actual rate controlling step was film diffusion for the whole process...
