Abstract—Potentially toxic trace elements such as Lead Pb(II)
and Copper Cu (II), with high levels in water are very serious
problem in many places around the world, sometimes in
relation to natural sources and in other cases to anthropogenic
ones. Adsorption process is among the most effective techniques
for removing of many heavy metal (HM) ions from different
types of water. In this study, an attempt has been made to
investigate the efficiency of granular activated carbon (GAC)
and powder activated carbon (PAC) obtained from easy
available agricultural by-products dates stones (DS) in
removing of Pb (II), Cu (II) from their aqueous solutions using
batch mode technique. During the removal process, the effects
of solution pH, HM concentrations and contact time, and
adsorbent concentration, on adsorption efficiency by both GAC
& PAC were studied. Under the experimental conditions, the
removal efficiency of such metals by PAC was 83%, 91%
showing preference over GAC which had a removal efficiency
of 76%, 82% respectively.
