Adsorption of Pb(II) Ions on Teak Leaves Activated Carbon- A Kinetic and Equilibrium Study

In the present study, attempts have been made to use teak leaves (Tectona grandis) for the preparation of activated carbon with a view to use it in the treatment of wastewater and industrial effluent. The air-dried powders of teak leaves are carbonized using sulphuric acid and characterized by the methods suggested by the Bureau of Indian Standards. It has been planned to study about the nature of the surface of the adsorbent using Scanning Electron Microscope and FTIR. A comparative study of the experimental adsorbent material with commercial activated carbon, lignite and some other activated carbons procured from waste materials has revealed that the experimental adsorbent material is economically feasible and easily available one. In the present investigation, the activated carbon prepared from Teak Leaves (TLAC), has been used as the adsorbent and carried out batch mode experiments to study the effect of contact time on the removal of lead with the variation of the dose of the adsorbent. Models such as Lagergren, Bhattacharya-Venkobachar, Langmuir and Freundlich were tested and the results are interpreted
