Abstract
Removal of zinc from waste waters using new biosorbents derived from Terminalia Arjuna, Atlantia Monophylla (L) Correa and Madhuca Indica plants
Author(s): K. Papodu, Y. Hanumantha Rao and K. RavindhranathThe surface sorption nature of bio-adsorbents derived from plant materials of Terminalia arjuna, Atlantia monophylla (L) Correa and Madhuca indica plants have been probed towards the removal of Zinc ions from simulated polluted waters by varying the physicochemical parameters such as pH, sorbent concentration and time of equilibration and the extractions conditions have been optimized for the maximum removal of Zinc ions from waste waters. The extractions have been found to be pH sensitive. The optimum sorbent dosage, time of equilibration and % of removal have been found to be in the order leaves > barks > Ashes for the three plants studied. The effect of the co-ions on the % of extraction of Zinc has been studied and found that the common anions and monovalent ions are marginally interfered while cations like Cu2+ and Ni2+ interfered to some extent but Al3+ interfered markedly. The developed methodologies have been successfully applied to the samples collected from real polluted lake waters and industrial effluents.
