The Contamination of water by toxic heavy metals through the discharge of Industrial wastewater has been causing worldwide concern in the last few decades. Metals that is significantly toxic to human beings and ecological environments. The concentrations of toxic metals in wastewater effluent are higher than permissible discharge levels. Because of all these reasons and some definite regulations measures of precaution, it becomes necessary to remove the heavy metals from wastewater by an appropriate treatment before releasing them into the environment. Azadirachta Indica is used as an adsorbent for the removal of heavy metals from the textile wastewater. The adsorbent exhibits very high adsorption potential for removal of chromium which was achieved maximum at 90% in pH of range 1 to 10. The equilibrium data were fitted well by the Freundlich and Langmuir isotherm models.
