Removal of Ni from its aqueous solution by using low cost adsorbent prepared from wood apple shell.

In present study, micro porous activated carbon was developed from Limonia acidissima (Apple wood) fruit shell in very simple manner and applied for removal of Ni from aqueous solution. The results of study indicate that the prepared adsorbent was very effective in removal of nickel from its aqueous solution. More than 80 % percentage removal of nickel was found to with an effective dose of adsorbent. The adsorbent is prepared from waste material and conveniently used for the treatment of industrial waste water containing nickel heavy metal. The effect of pH, contact time , concentration and amount of adsorbent dose was also studied and it was found that maximum adsorption occurred at pH 2 and at 180 minutes. The study clearly shows the dependence of adsorption on concentration of the adsorbate solution.
