Lead is one of the most used metals in various factory activities, leading to significant environmental and public health concerns due to soil and water contamination. This study aims to evaluate the adsorption properties of a chelating ion exchange resin functionalized with an iminodiacetic acid group for the removal of Pb and Cd from wastewater. A batch procedure was employed to investigate the adsorption of these metal ions at varying concentrations and contact times. Subsequently, a dynamic system using a column setup was implemented for the continuous removal of Pb from industrial effluents. Results indicated that the adsorption rates of Pb and Cd increased with higher initial concentrations and extended contact times, with maximum capacities reaching 137.40 mg/g for Pb and 90.40 mg/g for Cd. In a column application, the resin effectively eliminated Pb concentration from 22 mg/L to 0.014 mg/L during initial cycles, exceeding regulatory discharge limits. The resin demonstrated significant reusability after undergoing regeneration with 1 M HCl, indicating its effectiveness and potential for repeated use in industrial wastewater treatments. Overall, the findings highlight the efficiency of the chelating resin in lead removal and its viability for industrial applications.
