Releasing of heavy metals into the environment is a worldwide major problem. The adsorption process has been preferred to remove lead ions from water as its low initial cost, simplicity, and ease of operation. In Egypt, sawdust is produced continually as a waste of wood. The retention profile of lead ions from aqueous solutions onto the solid sorbent sawdust has been investigated in a batch system. The characterization of sawdust was performed using furrier transform infra-red spectrum (FTIR) and scanning electron microscope (SEM). Different factors as contact time, adsorbent dose, pH, temperature, and initial metal concentration on lead removal have been studied. The most effective method for lead removal from water was applied using wood sawdust at 40 minutes contact time, 7pH, 10oC, and 0.6g/100ml sawdust dose. The maximum removal percentage of lead was 85%. This low cost and natural bio-adsorbent successfully removed lead ions from water and can be used for water treatment.
