Activated carbons prepared from two bituminous coals were used to adsorb phenol in aqueous solutions. The major diΓΎ erence between the coal precursors is the oxygen content. The carbon preparation consisted of carbonization of the coals followed by activation in to various CO 2 extents of burn-oΓΎ .
Adsorption at 298 K of phenol, p-cresol, m-chlorophenol, m-aminophenol, and p-nitrophenol from aqueous solutions on activated carbons obtained from an original and a demineralized bituminous coal has been studied. The adsorption capacity of the activated carbons depended on the surface area and poro
