Abstract

In this study, Magnetic Fe3O4-walnut sawdust nanocompositewas synthesized and used for removal of lead from aqueous solution. The size, structural, optical and morphological properties of nanoparticles have been analyzed by Scanning Electron Microscope )SEM) and Dynamic Light Scattering method. The effect of pH, contact time, adsorbent dose, initial concentration, ionic strength and the effect of temperature on the adsorption was checked out in a batch process mode. Using the equilibrium constants obtained at different temperatures, the thermodynamic results parameters were calculated as ∆G, ∆H and ∆S. The thermodynamic parameters showed that the uptake of lead is spontaneous and endothermic. The data were fitted with the Langmuir and Freundlich equations to describe the adsorption equilibrium. The maximum adsorption capacity by using Langmuir equation was calculated 12.99 mg/g. The kinetic data followed by Pseudo second. Owing to such outstanding features, Magnetic Fe3O4-walnut sawdust nanocompositeproved the great potential in adsorption lead removal from aqueous solutions.
