Water pollution due to organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) is a serious issue because of high toxicities, mutagenic and carcinogenic. Among various water treatment methods, adsorption could be a promising technique for removing organic pollutant from aqueous environment. Many agricultural waste materials used include fruit wastes, sugar cane bagasse, coconut shell, wood ash and rice husk have prospective future to be utilized as biosorbent due to their cost effectiveness, abundant availability, high biosorption capacity and renewability. The main objectives of this study were to prepare activated carbon derived from rice husk, and to ascertain the potential of adsorbent for removal PAHs in aqueous solution. The activated rice husk activated carbon was activated by impregnating rice husk with ZnCl2, and then was heated at carbonizations temperature of 3000C. Effects of dose adsorbent, pH, and contact time on adsorption of PAHs have been examined. Physical characterization of the activated carbon obtained was performed by scanning electron microscopy (SEM) and Fourier Transform Infrared (FT-IR). The result revealed that equilibrium time is found to be 1 hours at pH 3. SEM analysis showed that the adsorbent surface was irregular, rough, and highly porous structure. The FT-IR spectra indicated the presence of hydroxyl group at 3425 cm-1 and carbonyl group at 1627 cm-1. The activated carbon derived from rice husk is important to attempt providing the future perspective of low cost adsorbents that effectively removes PAHs from aqueous environment.
