Abstract Lead (Pb +2 ) ions considered a crucial neurotoxic heavy metal result in serious troubles the live biological environment including poisoning, and liver kidney shortage, addition to anemia, hepatitis, encephalopathy, renal syndrome. In current study, biomass of Zea mays (ZMS) was prepared as biosorbent for elimination Pb from aquatic batch mode relevant contact time, pH solution, dose, temperature. The characterized using an SEM microscope coupled with EDX, FTIR, XRD, BET surface area analysis investigate modification chemical structure biosorption system. According experiments, supreme capability ZMS approaches 16.9 mg/g 180 min at = 5.5. evaluation kinetics reveals that by better described pseudo-second-order kinetics. addition, nonlinear regression Freundlich, Langmuir, Temkin, Elovich isothermal models modeled equilibrium data, it deduced Langmuir isotherm provides fit than based on correlation coefficient values. thermodynamic factors were calculated this process which lead are sequestered ZMS. these factors, elucidated onto sponge is exothermic spontaneous. Monte Carlo (MC) simulations conducted screen adsorption competence pigments ligands adsorption. outputs experimental simulation studies proved potentiality promising eliminating metallic elements aqueous media.
