- Removal of zinc from aqueous solutions by dry plant leaves
- Published at:PROCESS SAFETY AND ENVIRONMENTAL PROTECTION Volume: 81 Issue: B4 Pages: 236-242 Published: JUL 2003
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.
