Abstract

Introduction: Heavy metals with their entry into the food chain and water resources are considered as a serious threat to human health. This study aimed to survey FE3O4 NANOPARTICLES modified with ORANGE PEEL efficiency in removal of LEAD and COPPER ions from aqueous environments.Methods: This experimental research was implemented during the year 2012 and FE3O4 NANOPARTICLES were used as adsorbent which were modified with ORANGE PEEL. Experiments were implemented under batch process by adsorbent (300 mg/L) with changing effective factors such as contact time (20, 40, 60, 80, 100, 150, 200, 250 minutes), pH (3-12), temperature (20, 30, 40, 50o C) and concentration of LEAD and COPPER ions (10, 20 mg/L). Kinetic ADSORPTION and thermodynamic parameters were investigated according to the conditions of the theory.Results: The maximum ADSORPTION capacity of LEAD and COPPER ions on the adsorbent under optimum condition (contact time= 40 min, pH= 6 and temperature= 50o C) was obtained which turned out to be 70.06 and 71.21 mg/g respectively. ADSORPTION of LEAD and COPPER ions was according to pseudo-second-order kinetics and with relation to coefficients equal to 0.91 and 0.99 respectively and being fit with Langmuir ADSORPTION model. Positive values of enthalpy (DHo) indicated the endothermic nature of the process and negative values of free energy (DGo) thus indicating the spontaneity of the process.Conclusion: ADSORPTION of LEAD and COPPER ions on the adsorbent under optimum condition turned out to be 98%. The results showed that FE3O4 NANOPARTICLES modified with ORANGE PEEL can be an effective adsorbent for the removal of LEAD and COPPER ions from contaminated water resources.
