Industrial Wastes as Adsorbents for the Removal of Chromium from Waste Water : A Review

G. RAVI KISHORE, R. PADMA SREE and D. KRISHNA


The contamination of water by toxic heavy metals is a worldwide problem. The presence of hexavalent chromium in waste water is a potential hazard to aquatic life and humans. Biosorption of heavy metals is an important technique used in the removal of toxic metals from various sources like industrial waste, aqueous systems and municipal waste waters. Metal removal technique using industrial waste as adsorbents are cheap because of the low cost of adsorbents used and many represent a practical replacement to conventional processes. There are various mechanisms such as kinetic models and adsorption isotherms employed for the efficient removal of hexavalent chromium from various sources. The present review discusses brief findings of hexavalent chromium removal with the maximum metal uptake by using industrial waste as adsorbents.
