Removal of toxic metals from industrial wastewaters is essential from the stand point of environmental pollution control. Among all heavy toxic metals nickel, mercury, lead, chromium and cadmium are in limelight due to their major impact on environment. Heavy metals have a tendency to accumulate and end up as permanent additions to the environment. It is evident that adsorption using biomaterials is an effective method for the removal of nickel(II) from industrial wastewaters. The usage of biomaterials is simple economically viable. By this method about 100% of Ni(II) removal is possible. From our studies it is evident that as adsorption time increases % removal of Ni(II) also increases. As the temperature increases the % removal of Ni(II) decreases. The activity of adsorbent is maximum and high % removal of Ni(II) was identified at a pH of 10 because of chemical precipitation of Ni.
