The removal of toxic heavy metal ions such as lead and zinc from industrial and mining wastewaters has been widely studied because their existence in surface and underground water is responsible for several types of health problems caused to animals and human beings.Also, there are some organic compounds, which must be prevented from reaching in drinking water from various sources of pollution.For these reasons in this paper the experiments were conducted to study the ability of activated carbon for removal of Pb(II), Zn(II), C6H6, C6H5-CH3 from water.In addition to the data from the literature showing the actived carbon efficiency for removing of the organic nature pollutants from water, in this article the study is done also on inorganic toxic pollutants (lead and zinc heavy metals) that can exist in water.The removal efficiency of the tested activated carbon used as adsorbent towards the tested pollutants decreased in the following order: COD (benzene, toluene) > Pb(II) > Zn(II).
