Removal of Cr(Vl) is important for the safety of aqueous environment, it being carcinogenic and toxic to aquatic life. Various methods used for removal of Chromium ions include chemical reduction and precipitation, reverse osmosis and ion exchange and adsorption on activated carbon or similar materials. But, all these methods suffer from severe constraints, such as incomplete metal removal, high reagent or energy requirements, generation of toxic sludge or other waste products that require safe disposal. Adsorption techniques for removal of Cr(VI) has been reported by various researchers in...
