Abstract

The biosorption characteristics of Pb (II) ions from aqueous solution using black walnut (Juglan nigra) seed husks (WSH) biomass were investigated using batch techniques. The effects of pH, contact time, initial metal ion concentration, and temperature were studied. The Langmuir, the Freundlich and the Temkin isotherms were used to analyze the equilibrium data. It was found that adsorption of Pb (II) ions onto WSH, was best described by Freundlich adsorption model. Biosorption kinetics data were fitted using pseudo-first-order and pseudo-second-order models, and it was observed that the kinetics data fitted better into the pseudo-second order model. Thermodynamic parameters such as standard Gibbs free energy (ΔG0), standard enthalpy (ΔH0) and standard entropy (ΔS0) were evaluated. The result showed that biosorption of lead (II) ions onto WSH was spontaneous and endothermic in nature. The FTIR study showed that the following functional groups: O-H, C=O, C-O, C-H and N-H were involved in binding Pb(II) ions to the biomass.
