Pecan shell chars were activated using steam, carbon dioxide (CO 2 ), or phosphoric acid (H 3 PO 4 ) to produce granular activated carbons (GACs). The GACs were characterized for select physical, chemical and adsorption properties. Air oxidation of the GACs was used to increase copper ion (Cu 2 ) ad

✦ Synopsis
Chars, prepared by pyrolysis of prune pits at I or lS"C/min to 500, 700 or 9OO"C, were subsequently gasified by CO, at 900°C. Pyrolysis conditions did not significantly affect the porosity developed for a given mass loss due specifically to gasification reactions, i.e. excluding additional pyrolytic losses.

## Abstract Activated carbons play an important role in the purification of air and of water. Whereas vapors are adsorbed by a micropore filling process, the removal of sparingly soluble species such as phenol and its derivatives is limited to the coating of the effective surface of the material. T
