摘要：
Rice waste - low cost agricultural waste has been utilized as the adsorbent for the removal of hexavalent chromium from aqueous solution. Adsorption capacity of rice wastes and interaction of the different functional groups were studied. Batch adsorption technique was employed to optimize the process parameter. A detailed FTIR characterization of the fresh adsorbents and Cr(VI) loaded adsorbents were carried out. The results show that the different functional groups such as surface hydroxyl, alkene, aromatic nitro, carboxilate anion and silicon oxide etc were responsible for the adsorption process.
