“…Babel and Kurniawan (2003) reviewed the use of lowcost adsorbents for heavy metals uptake from contaminated water. Researchers investigated industrial by-products such as lignin (Betancur et al, 2009;Reyes et al, 2009), diatomite (Sheng et al, 2009), clino-pyrrhotite , lignite (Mohan and Chander, 2006), aragonite shells (Kohler et al, 2007), natural zeolites (Apiratikul and Pavasant, 2008a), clay (Al-Jlil and Alsewailem, 2009), kaolinite (Gu and Evans, 2008) and peat (Liu et al, 2008a), etc. Jiang et al (2010) investigated the kaolinite clay obtained from Longyan, China to remove heavy metal ions Pb(II), Cd(II), Ni(II) and Cu(II) from wastewater.…”

“…Several works have been focused on the application of various adsorbents for the removal of single solute heavy metal ion from the aqueous phase [8,9]. However, only a few publications are devoted to the binary or the multi-solute adsorption [9,10] that is more important to study and evaluated since single toxic metal species rarely exists in natural water and wastewater. Experimental work interested by heavy metal adsorption equilibrium could confirm the benefits of activated carbons prepared from olive stones adsorbent in single and binary solute systems.…”

A B S T R A C TIn the present work, activated carbon synthesized from olive stones was used for heavy metal ions (Cu(II), Ni(II), and Pb(II)) removal in single and binary aqueous solutions. The effect of initial solution pH was studied. The equilibrium isotherms for single systems were evaluated in terms of maximum adsorption capacity and adsorption affinity by the application of Langmuir model. Metal ions adsorption increases in the following order: Pb(II) > Ni (II) ≥ Cu(II). The examination of binary adsorption systems: Cu-Ni and Cu-Pb shows that the affinity of copper on the activated carbon surface was strongly dependent on initial concentration of nickel and lead. Copper adsorption was found to increase in the presence of nickel and to decrease in the presence of lead.

“…In ternary system, Cu(II) and Zn(II) were well fit both by the Langmuir and the Freundlich models, while Pb(II) correlated better with the Langmuir model. Liu et al (2008) studied the competitive adsorption of heavy metals on peat. The results showed that the adsorption isotherm fit the Langmuir model very well.…”

The removal of Cu(2+), Ni(2+), and Zn(2+) ions from their multi-component aqueous mixture by sorption on activated carbon prepared from date stones was investigated. In the batch tests, experimental parameters were studied, including solution pH, contact time, initial metal ions concentration, and temperature. Adsorption efficiency of the heavy metals was pH-dependent and the maximum adsorption was found to occur at around 5.5 for Cu, Zn, and Ni. The maximum sorption capacities calculated by applying the Langmuir isotherm were 18.68 mg/g for Cu, 16.12 mg/g for Ni, and 12.19 mg/g for Zn. The competitive adsorption studies showed that the adsorption affinity order of the three heavy metals was Cu(2+) > Ni(2+) > Zn(2+). The test results using real wastewater indicated that the prepared activated carbon could be used as a cheap adsorbent for the removal of heavy metals in aqueous solutions.
