ABSTRACT

 

The adsorption process is being widely used by various researchers for the removal of heavy metals from wastewater and activated carbon has been frequently used as an adsorbent. In recent years, the need for safe and economical methods for the elimination of heavy metals from contaminated waters has necessitated research interest towards the production of low cost alternatives to commercially available activated carbon. In the present investigation, feasibility of different non-conventional bio-adsorbents of plant and microbial origin waste carrot juice pulp, waste tea leaves, wood powder (saw dust), paper mill sludge and microbial bio-waste from fermentation industry were tested for the removal of metals Pb, Zn, Ni and Fe from wastewater in single metal state and multi-metallic state and were compared with activated carbon in order to develop inexpensive adsorbent.
