This study presents the adsorption of Pb(II) ions from aqueous solutions and describes adsorption effectiveness of RetamaMonosperma Powder (RMP),in removing Pb(II) ions in order to consider its application in wastewater purification.The batch method has been employed using metal concentrations in solution and the percentage adsorption was determined for the adsorption system as a function of adsorbate concentration. Effects of the temperature of the Pb(II) ion solution, pH, contact time, metal concentration, and adsorbent loading weight on the removal process were also investigated. Langmuir, Freundlich isotherms were applied to experimental data and the goodness of their fit for adsorption was compared. Thermodynamic parameters, like enthalpy (ΔH) and the entropy (ΔS) were also calculated.The results of the present investigation indicate that Retama Monosperma( RMP),has high potential for the removal ofPb(II) ions from aqueous solutions, and resultant data can serve as baseline data for designing treatment plants at industrial scale
