The release of large quantities of heavy metals into the natural environment has resulted in a number of environmental problems. The treatment technologies that have been used for treating heavy metal bearing waste streams, such as chemical precipitation, adsorption, ion-exchange, and solvent extraction, have been found to be limited, involve high capital and operational costs and may also be associated with the generation of secondary wastes that also present treatment problems biosorption of heavy metals offers a potential alternative to existing methods for detoxification and recovery of these components from industrial wastewaters and is a subject of extensive studies. The biosorption of Iron(II) and Zinc(II) both ions in combination, by flyash was studied in a batch system as a function of initial pH and dual-metal ion concentrations. The working pH values were determined to the selective uptake of metal ions. Multi component biosorption studies were performed at the initial pH values. It was observed that the biosorption kinetics and equilibrium uptakes of Iron(II) and Zinc(II) ions in binary mixtures changed due to the initial biosorption pH and the presence of the other component.
