Heavy metal contamination exists in aqueous waste streams of
many industries, such as metal plating facilities, mining operations
and tanners [1]. Copper pollution especially, arises from copper
mining and smelting, brass manufacture, electroplating industries
and excessive use of Cu-based agro-chemicals. Copper along with
arsenic and mercury, is recognized as the highest relative mammalian
toxic and continued inhalation of copper containing sprays
is linked with an increase in lung cancer among exposed workers
[2]. Hence, the removal of copper from aqueous solutions is
extremely important. Adsorption is highly effective and economical
method to remove heavy metal ions from aqueous solutions. Activated
carbons, with their high surface area, microporous structure
and chemical nature of their surface, are potential adsorbents for
the removal of different heavy metals from industrial wastewaters
