Background: Lead is one of the priority toxic pollutants of industrial wastewater which is discharged to the environment by some of industries such as battery, paint, weapons and glassmanufacturing. In this study, use of magnetic iron oxide nanoparticles (maghemite) for the removal of lead from synthetic wastewater of battery industry was investigated.Methods: The influence of various factors such as pH, initial concentration of lead and contact time on lead removal from synthetic wastewater by the nanoparticles was valuated. After separating the adsorbent by magnetic field, remaining lead concentration was measured by atomic absorption spectroscopy (Perkin Elmer 2380). The results were analyzed by the SPSS software, Version 18.Findings: Results showed that in the pH value of 7, initial concentration lead of 50 mg/L , 0.1 g/L nano maghemite dose, contact time of 40 min and stirring speed of 150 rpm, 63.91% lead removal was obtained. Adsorption capacity of the nano maghemite was 61mg/g.Conclusion: In optimum condition, maghemite nanoparticles show high adsorption capacity; and rapidly and effectively eliminates lead ions from watewater. Its efficiency for lead removal was directly related to pH and contact time and reversely related to initial concentration of lead. The absorption model was fit well to the Freundlich isotherm.Key Words: Lead, Adsorption, Maghemite nanoparticles, Battery industry
