Abstract

Some of the authors of this publication are also working on these related projects: Waste water treatment View project heavy metal removal by using nano particles View project Yogeshwaran Venkatraman Sri Krishna College of Engineering and Technology Abstract Heavy Metal recovery is one of the serious problem in this world. Many Industries were discharged their effluent into the water bodies (lakes, rivers etc.,) without any prior treatment. Tanneries are the type of industry which delivers the effluent with high concentration of Hexavalent Chromium (Cr 6+). It should directly affects the lungs and causes the cancer. The present study has reviewed the removal of Hexavalent Chromium (Cr 6+) from various natural adsorbents.
