The presence of hexavalent chromium in waste water is severe hazard to aquatic life and humans. Biosorption of heavy metals is an important technique used in the removal of chromium from various sources like industrial waste, aqueous systems and municipal waste waters. Chromium metal removal technique using non-conventional adsorbents such as microorganisms 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 living and non-living microorganisms as adsorbents.
