摘要：

Heavy metals such as arsenic (As) and lead (Pb) can have irreversible impacts on human health as water pollutants. Activated carbon-based materials are anticipated to remove them effectively from water. The research examines the possibility of a sustainable and low-cost adsorbent in removing heavy metals from aqueous solutions with activated carbon (AC) made from waste materials (discarded facial masks) which was incorporated with Fe3O4, producing ACW-Fe3O4. This material was analyzed with XRD, FTIR, FE-SEM, BET, and EDS at different temperatures, contact time, adsorbent dosage, adsorbent concentrations, and pH as experimental variables. Optimum conditions of adsorption revealed pH = 5 for Pb, pH = 7 for As, and a contact time of 60 min with an adsorbent dosage of 0.005 g at 298 K. The maximum adsorption capacities were achieved 233.89 mg/g for Pb and 186.29 mg/g for As. Additionally, Langmuir and pseudo-second-order models had better fits to the experimental data than other models tested in this study regarding isotherm and kinetic modeling. It was revealed from the thermodynamic studies that the adsorption process is exothermic and spontaneous. Lastly, the reuse potential of the adsorbent after 6 cycles showed 86 % and 78 % reusability for Pb and As, respectively. © 2025
