Abstract
Adsorption techniques are widely used for the removal of various classes of pollutants from water due to their mild and facile operating conditions. The operations involved in the adsorption techniques are environmentally friendly, economical, highly selective on pollutants, highly efficient and easily operative. However, the adsorption of heavy metals from water using biomaterials (biosorption) is a relatively new and interesting technique which holds a great potential. Its effectiveness in lowering the heavy metals concentration to sub-ppb levels is appealing and has attracted increasing attention. The technique is believed to replace the existing technologies in the near future. This chapter discusses the prospects of biomaterials in the removal of heavy metals from waste water, the modification techniques that can enhance biosorption efficiency, and the factors influencing the biosorption processes.
