✦ Synopsis

Adsorption studies of Zn 2+, Cd*+, and Cu2+ from aqueous solutions at 293 K and 313 K on three activated carbons are reported. These carbons were obtained by activation of almond shells, olive stones, and peach stones by heating in CO, at 1123 K. From these isotherms some adsorption parameters have been determined. The influence of the solution pH on the adsorption processes has been studied. The extent of adsorption in the presence of Cl-, CN-, SCN-, or EDTA has been also investigated. The adsorptive behaviour of these activated carbons is explained on the basis of their chemical nature and porous texture.

## 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.
