Heavy metal ions removal from an aqueous solution using an adsorbent derived from walnut shell: Equilibrium, kinetic and thermodynamic studies

A modified adsorbent for the removal of heavy metal ions (HMI) Pb2+, Cd2+, Cu2+, Ni2+, and Co2+ was synthesized from carbonized walnut shells (Juglans regia L.) pretreated with sodium carbonate (Na2CO3). By selecting the optimal parameters for the chemical activation of the raw materials (temperatur...
