摘要：

Adsorption studies of Zn**2** plus , Cd**2** plus , Cu**2** plus 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//2 at 1123 K. The influence of the solution pH on the adsorption processes has been studied. The extent of adsorption in the presence of Cl** minus , CN** minus , SCN** minus , or EDTA has been also investigated. The adsorptive behavior is explained on the basis of the chemical nature and porous texture of the carbons.
