Kinetics and Equilibrium Studies on Biosorption of Zinc onto Terminalia catappa Leaf Powder
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 4
Abstract
The biosorption of zinc ions from aqueous solution by Terminalia catappa L. was studied in a batch adsorption system as a function of pH, contact time, zinc ion concentration, biosorbent dosage and biosorbent size. The biosorption capacities and rates of zinc ions onto Terminalia catappa L. were evaluated. The Langmuir, Freundlich and Temkin adsorption models were applied to describe the isotherms and isotherm constants. It was determined that the best fitted adsorption isotherm models were obtained in the order: Langmuir>Temkin>Freundlich isotherms. The kinetic experimental data were properly correlated with the second-order kinetic model.
