Heavy metal ions, are non-biodegradable, high toxic tendency, and have serious hazardous effects on the health of humans. Then, removing them from the environment using different techniques is necessary. Several routes are expensive, low-efficient, and require a long time to achieve adsorption equilibrium. In this paper, novel chitosan-based composites CS/CL@An-1 and CS/CL@An-2 were synthesized, characterized by FT-IR, DSC, XRD, and SEM, and applied as new adsorbents in batch experiments for the removal of Pb
