Usefulness of Biomaterial prepared from Dry leaves of Pinus gerardiana in the removal of Nickel(II) from aqueous solution
Abstract
In the present study the dry leaves powder of Pinus gerardiana has been used as metal adsorbent to remove nickel ion from aqueous solution. The adsorption characteristic of nickel(II) ion bio-sorbent were evaluated as a function of pH, contact time and initial metal ion concentration. The adsorption isotherm data confirmed to Freundlich isotherm . The percentage removal of nickel ion increases with increase in the pH from five to seven and the maximum sorption takes place at pH seven. The study has demonstrated that the easily available biomaterial can be a cost effective and environmental friendly bio-sorbent in the removal of toxic heavy metal from waste water.
