β-cyclodextrin (β-CD) and activated carbon (AC) were used as starting material to hydrothermally synthesize new hybrid material. It was found that hybrid carbon material, rich in oxygen-containing functional groups like -C=O-, -OH, etc., can be effectively well-dispersed on the surface and at the entrance of the pores of AC. The carbon composite that was obtained exhibited a remarkably enhanced adsorption capacity for Pb (II) per unit mass, reaching a value twice that of non modified AC. The high specific adsorption capacity of the composite can be explained by the abundant surface oxygen-containing functional groups and the relatively well-developed pore structure. In addition to this, the adsorption process studied was best described by the pseudo-first and pseudo-second order kinetic model.
