Polycyclic aromatic hydrocarbons (PAHs) have a great concern as apersistent organic pollutant in the aquatic environment due to their high toxicities, mutagenic and carcinogenic properties. Among various water treatment methods, adsorption could be a promising technique for removing organic pollutant from the aquatic environment. The present study proposes a low-cost activated carbon from rice husk and its potential as an adsorbent for removing PAHs (phenanthrene and fluoranthene) in the aquatic environment. Physical characterization of the activated carbon obtained was performed by Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FT-IR). Effects of dose adsorbent, pH, and contact time on adsorption of PAHs have been investigated. 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 3205 cm-1 and carbonyl group at 1565 cm-1. The result revealed that equilibrium time on phenanthrene and fluoranthene at pH 3 is found to be 60 and 30 minutes, respectively. The study shows that activated carbon from rice husk has a future perspective of low- cost adsorbents which effectively removes PAHs from the aquatic environment.
