The results revealed that the Ch-Z composite exhibited excellent adsorption performance for Pb2+ ions. The maximum adsorption capacity was found to be 275 mg g−1 at pH 4.5, Ch-Z composite dose of 5 g/L and an initial Pb2+ concentration of 1000 mg/L for 24 h. The adsorption equilibrium data and its kinetics followed a Langmuir and PSO models. Furthermore, thermodynamic parameters were determined, indicating that adsorption was spontaneous and endothermic. MC simulations were used to investigate the interaction between Pb2+ ions and the modeled composite. The considerable negative adsorption energy values confirm the strong affinity between the adsorbate molecules and the adsorbent surface. Overall, the Ch-Z composite adsorbent exhibited remarkable potential to remove Pb2+ ions from wastewater.en10.1016/j.molliq.2023.123310info:eu-repo/semantics/restrictedAccessChitosan, Zeolite, Composite beads, Pb2+ ions, Adsorption, MC simulationsArticle3911233221233102-s2.0-85174485318N/AWOS:001104406100001Q1
