Preferred Abstract (Original): 

Removal of zinc from aqueous solutions by 15 species of plant leaves was studied. The maximum efficiency of removal was found to be by walnut and poplar leaves at pH 6 with a maximum removal of 82%. Increasing the concentration of plant leaves increased the removal of zinc up to a limit. Agitation of solution increased the efficiency of the removal process. The presence of competing and complexing agents affected the removal process negatively but also positively in few cases.
