The rapid industrialization during last few decades without any concern for its impact on the environment has put the survival of living beings at stake. Organic and inorganic compounds either deliberate through industrial emissions or accidental through chemical or oil spills etc. released into the environment. The heavy metals such as Pb, Cr, Cd, Ag, As, Cu, Ni, V, Co Hg, Se and Zn are introduced into water streams from various industries viz. refining of ores, incinerators, electroplating, paints, mining, alloys, batteries, pesticides, paper industry, leather tanning, sludge disposal, organo-chemicals, petrochemicals, fertilizer industries, automobiles, metal processing etc. Biosorption using low cost biosorbents has been found considerably effective for removal and recovery of heavy metals from aqueous streams. Present studies involve the investigation of biosorption potential of selected biomaterials (selected on the basis of cost, abundance in availability and physic-chemical properties) for sequestering heavy metals Cd(II), Cu(II), Pb(II) and Cr(VI) from simulated aqueous solutions and analyse the adsorption kinetics for this heavy metal removal.
