摘要：

The main goal of this study was to evaluate the performance of two new adsorbents, ash and Fe nanoparticles loaded ash (nFe-A) for the removal of Pb(II) from aqueous solution. Batch experiments were performed as a function of various experimental parameters. The adsorption studies included both equilibrium adsorption isotherms and kinetics. Equilibrium data fitted very well with the Langmuir isotherm model. Kinetics studies showed better applicability for pseudo-second-order model for both adsorbents. The regeneration studies showed promising regeneration potential of these adsorbents. The breakthrough capacities of ash and nFe-A for Pb(II) removal was found 25 and 30 mg g(-1), respectively.
