Water pollution caused by heavy metal ions became a major problem for the environment and has become cause of concern for engineers. The damages caused to the environment is due to industrial and domestic waste water and it adversely affecting the human health. Different heavy metal ions have very adverse effect on human and aquatic life. Chromium is one of the most important heavy metal ion to concern, it is carcinogenic in nature and also contaminates soil and groundwater. Various different natural adsorbents are being investigated and are found to be very effective for Chromium removal. Adsorbents like sawdust, groundnut hull, agriculture waste, coffee husk and neem leaves found to be very effective against chromium. The review article presents the effect of the above mentioned adsorbent on hexavalent chromium under the parameters of Effect of pH, Effect of contact time and Effect of adsorbent dosage under batch scale study.
