Kinetic and Thermodynamic Studies on Biosorption of Lead ions by Chemically Modified Sawdust

Authors(2) :-Asha. R, Avila Thanga Booshan. S

The problem of removing pollutants from water is an important process and is becoming more important with the increasing of industrial activities. One of the most important environmental problems is water resources pollution by heavymetals. Biosorption is affordable adsorbents for the removal of heavy metals from aqueous solutions. This study explores the adsorption potential of Pb(II) by acid modified sawdust in aqueous solution. The influences of several main parameters such as pH and adsorbent dosage were studied. The adsorption kinetics were analyzed by pseudo first order and pseudo second order kinetic models. Thermodynamic parameters including changes of free energy (ΔG), enthalpy (ΔH) and entropy (ΔS) during the biosorption were determined.
