摘要:In this study, siru-chstiM ill, frutis and seeds (PSCFS) was used as an adsorbent for P b(II) ions rem oval from water solutions. The effect of various experimental parameters was investigated using a batch adsorption technique. In the adsorption experimental, temperature, contact time and concentrations effects upon Pb (II) ions on PSCFS were thoroughly examined at pH 5.2. Results show that a temperature value of 45 °C is favorable for the adsorption of Pb (II) ions. The isotherm al data could be w ell described by the Freundlich equation. The kinetic data fit w ell w ith the pseudo-second-order kinetic model. The adsorption capacity of PSCFS was found to be 14.97°1 mg g 1 at 45 °C according to pseudo-second-order model data. Thermodynamic parameters such as activation energy (Ea) and change in the free energy (AG°), the enthalpy (AH°), and the entropy (AS°) were also evaluated. The all adsorption process was endothermic and spontaneous. The results indicate that PSCFS could be employed as low-cost m aterials for removal from water of Pb (II) ions.
