Abstract:

A process for the hexavalent chromium removal by a novel nano adsorbent is discussed in this work. This paper has a double purpose. The first part described how to obtain a nanosize adsorbent using a different material Sapindus emarginata rind. Here the preparation of novel activated carbon from the rind by pyrolysis method is explained. Chemical analysis for the nano adsorbent is carried out and analyzed. The morphology of the prepared nano activated carbon is characterized by SEM, TEM and XRD. In the second part removal of hexavalent chromium by the above nano absorbent is studied. The influence of the following parameters such as pH, agitation time and adsorbent dosage is taken into account for the batch experiments. The adsorption efficiency of the chromium removal from tannery effluent also studied. The result showed that prepared nano adsorbent can be used efficiently for the treatment of tannery wastewater containing chromium.
