The toxic heavy metals are released in the environment due to rapid industrialization and urbanization processes and are a great threat to environment. Adsorption is an effective technique for the removal of heavy metals from the aqueous solutions. Now a day various natural adsorbent have been used by many researchers as a cheaper method for the treatment of water. In the present study the Alexandrian laurel oil cake is used as the adsorbent for the removal of Zn (II) from the aqueous solution. The parameters studied include contact time, adsorbent dosage, initial concentration, and pH. The Zn(II) removal was attained using 3g adsorbent for 60 minutes with initial concentration of 3g/L and pH6. These findings concluded that Alexandrian laurel oil cake is a suitable for removing Zn(II) in heavy metal polluted water.
