【 摘 要 】

Problem statement: It is well documented that lead is one of contaminants of industrialwastewaters and its pollution exists in the wastewater of many industries. As a result, recent researchhas focused on the development of cost effective alternatives using various natural sources andindustrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues forrecovering heavy metals from contaminated industrial effluent has emerged as a potential alternativemethod to high cost adsorbents. In the present study, adsorption of lead(II) ions onto Orange Peel(OP), a typical agricultural byproduct, was investigated systematically with the variation in theparameters of pH, sorbent dosage, contact time and the initial concentration of adsorbate. Langmuirand Freundlich isotherms were used to analyze the equilibrium data. Kinetic and thermodynamicparameters were also calculated to describe the adsorption mechanism. Approach: The Orange Peel(OP) was obtained from a local market in the south of Jordan. The orange peel was cut into smallpieces using scissors. Then OP was dried at 100
