Removal of Chemazol Reactive Red 195 from aqueous solution by dehydrated beet pulp carbon

► Dehydrated beet pulp carbon as an adsorbent for removal of Chemazol Reactive Red 195 dye. ► Freundlich model well described the adsorption equilibrium. ► External mass transfer and intra-particle diffusion played an important role. ► Adsorption kinetics followed the pseudo-first-order kinetic model.
