摘要：
The adsorption of cationic and anionic dyes from aqueous solution by high surface area activated carbon prepared from grapevine rhytidome (as an abundant and low-cost bioresource precursor) was studied. The adsorption was studied from both kinetic and equilibrium point of view and the results were compared with the results of commercial granular activated carbon. Different kinetic and equilibrium models were used to analyze the experimental data. The adsorption capacity values were comparable for the prepared activated carbon and the commercial one. The results show that the low-cost prepared activated carbon can be effectively used for the removal of cationic and anionic dyes.
