Abstract
In the present work, an activated carbon material has been prepared from date pits to remove
zinc (Zn2+) and copper (Cu2+) from a wastewater. The effect of some parameters on adsorption
performance has been investigated. The optimization of operational conditions allowed
increasing the adsorption of Zn2+ ions from 33% to 85% and the adsorption of Cu2+ from 23%
to 70%. The optimum conditions found are a mass of adsorbent of 4g, a stirring speed of
500 rpm and a ratio of 15 for volume of liquid / mass of solid. It has been shown that the
adsorbent has more affinity to the copper ions than zinc ions and the modeling results gave
adsorption isotherms type “C”. The results also showed that the kinetics of zinc and copper ions
adsorption were described by a pseudo second-order rate model and controlled by the internal
diffusion which can be considered as limiting step that controls the rate transfer of these ions to
the solid surface
