This study aims to prepare and characterize of polystyrene/Zn-Al layered double hydroxide (LDH) nanocomposites. In addition to the adsorption capacity of the prepared nanocomposites was evaluated using Cd2+ and Pb2+ heavy metal ions. The synthesized nanocomposites were prepared using styrene monomer via in situ free emulsion polymerization. The prepared polymeric nanocomposites were characterized using FT-IR, XR D, TEM, and TGA. The prepared nanocomposites were investigated as adsorbent to remove both of Cd and Pb (II) fromaqueousmedia using atomic adsorption spectrometry. The results showed that the high concentration of LDHs exhibited high adsorption efficiency.
