ABSTRACT
The powdered biomass of Cicer arientinum has been converted in to cheap carbonaceous adsorbent by AR Sulphuric acid and AR. Nitric acid treatment. This adsorbent exhibits a good sorption potential for heavy metals like Ni2+ and Pb2+ from their mixture. Present work deals with removal and recovery of heavy metals like Ni2+ and Pb2+ from their mixture and chemical regeneration of the adsorbent material.
