loggergren’s adsorption dynamics for the removal of lead using egg shell as an adsorbent

The removal of heavy metals from industrial effluents and from waste water has become a subject of keen interest. Earlier reports reveal that an extensive research work has been carried out with a view to analyze the various possible removal techniques. This present work deals with the removal of lead from its aqueous solution using very cheap waste material – egg shell as an adsorbent. The process of removal was carried out by column and batch mode techniques. Experimental results exhibit that the removal was found to be enhanced by increasing the dose of the adsorbent and decreasing the size of the adsorbent. The results are interpreted in the light of Loggergren’s model.
